They must be coming from your input NMR restraints in some fashion. If you
add LISTIN=POUT to your run, you will get lots of debugging information about
each restraint. That should help you find out what is happening.

Or, find the atom numbers for O in residues and 17, and look in your restraint
files for those atom numbers. A lot depends on how you creating the DISANG
file in the first place.
