It appears the first screen displays RA rate in arcsec/sec but the second screen displays the RA rate in sec/sec?  Since there is 15 degrees in 1 hr RA to convert sec/sec to arcsec/ hr would be 11.06992 x 15 x 60 x 60 = 597775.   I cannot explain why it does that but that is what appears to be happening?
