What's SGPro is doing is correct.
It's correct to set astrometric engines (plate solvers) to J2000 and SGPro parses all mounts for EPCOH and A-P mounts always returns their EPOCH of JNow so that SGPro will properly convert from J2000 to JNow coordinates.

It seems SGPro is converting the J2000 to JNow, whatever the original format is.

What are you using to plate solve? If astrometry.net, make sure it is set to j2000...
