Why are you showing channel 1 but measuring channel 2? We can't see the signal being measured. Since it has almost zero deflection (5 samples high) I doubt it is valid to be taking any measurements from it. If you wish to measure the displayed channel 1 instead, then hit 1 to select it, and it will be measured.
Even then, the measurements might be great, as described in LIMITATIONS of xoscope(1):
The automatic measurements count zero crossings and divide to determine
the frequency and period. If these zero crossings are not "regularly-
periodic", these measurements could be invalid.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I have a screen shot of a 50Hz signal but xoscope shows 10K Hz. Aparently there is a 10K Hz noise on top of the 50K Hz

Should I file a bug report?

Thanks for pointing that out.
