TimeCode vs Exported Timestamps out ! can anyone help

Hi All , New to Cubase , been a hard couple of days getting going , just trying to Mixed and Cue and put the Wav in PT , and it was out of Sync . play back via MTC is fine . I found this dialog attach below . I have Neve seen anything like this , it seem I have to enter the TC manually in the insert Broadcast tab to get burnt TC , and then as you can see Cubase has set the wrong start time . should be 05.09.22 but its 05.09.56. I have no idea why , but if a zoom in and enter the correct start time it work ok … is the correct ?
