OK...

Problem Area 1, Bar 53:

Looking at the music, and looking at Rosegarden, I observe that the As in this 
measure are flat on the sheet music, but not in Rosegarden.  Shift+Click the 
first A, the second A, then the third A, hit the down arrow once, and now 
they're Ab across the board.  Repeat this for the other part that has the 
same problem here, and the dissonance in this section goes away.

(To pre-select that you want to enter a flat, click the flat icon on the 
accidental toolbar before clicking your note into being.

See if I had anything useful to say here:

Problem Area 2, Bar 62:

Looking at the music, and looking at Rosegarden, I observe:

    1 There is an extra set of redundant key changes at 63 in the first two
      parts

    2 Music has a key change cancelling what looks like Bb out to C major/
      A minor, but the notation you've entered has a key change to D major/
      B minor (two sharps)

    3 The dotted 8th/16th pairs were not entered correctly, and the rhythm
      appears to be off in a couple of different ways whenever these pairs
      occurred in the original

First, click the extra key signatures (problem 1) to highlight them, then hit 
the Delete key to remove them.  Next, change each of the errant B minor key 
signatures to A minor.  Double click the first B minor key signature, change 
it to A minor.  Select "Use specified key signature" and "Use current 
pitches" options for the dialog.  (See snapshot of dialog.)

Now find the errant sharp Cs and Fs, shift click on each of them to create a 
selection that contains all of them at once, and hit the down arrow once to 
flatten them.  (If you had a lot of to fix at once, you could use the 
selection event filter, or use the matrix editor, but since there are only a 
few notes I won't get into those alternatives.)

That's got the errant notes fixed.  Now if you want to correct the rhythm in 
bar 62, highlight the fourth pair of 8th notes from the left, which should 
have taken dots (there is a separate duration toolbar for dotted rhythms, 
incidentally).  With these highlighted, hit Ctrl+. to dot them.  (Ctrl+. 
cycles through no dots, one dot, two dots, no dots.)  Now highlight the next 
pair of 8th notes, and hit Ctrl+6 to change them into 16th notes.  Due to the 
way Rosegarden thinks, the extra space will show up on the right, and you 
will have to drag the pair of notes over to the right to nudge them into the 
correct place.  (This is flakey/buggy behavior, but we're not going to fix it 
anytime in the next months or years, so this is pretty much what you've got 
to work with.)

It looks like the rhythm in the second part in bar 63 is so far off you may 
have to delete some notes and re-enter them.  You have a 16th note and a 16th 
rest at the end, and I can't wiggle this back into shape.  Rosegarden is too 
confused.  It happens sometimes, but it's not hard to highlight and delete 
the last bit of this measure and click a few notes back into being, with the 
correct rhythms.

I don't see any Rosegarden bugs here.  Nothing major in any case.  You just 
need to play around a bit more, and rest assured that Rosegarden is perfectly 
capable of rendering the two bars you displayed here, and it really is all 
just, well, plain user error.

(Unfortunately, there are plenty of things out there that Rosegarden *can't* 
render correctly, but that isn't the problem here.)
