I found why the bug happens! The problem is with processing OCCURS in 
level 01 data items.
I suggest a workaround like this (according your code):

       01  date-table.
        02  date-table-reg occurs 20 times.
           05  dt-bk-cd                 pic 99.
           05  dt-memo-amt              pic s9(10)v99
                 sign leading separate.

Please, report me any other bugs found. I'm trying to make our compiler 
usable.
