A vcr counter rewinding issue?

Hello. I have a digilogic 2 vcr & dvd combo unit.
Amazingly I have managed to see and hear the picture on my smart TVs, using a scart cable from each, Using the av setting.
However, on some vhs tapes, which are mid way through I cannot fully rewind the tape, as it seems to reset to a 00:00 counter point that I didn’t set.
Is there any easy way to override the zero counter point please? I want to be able to log the tape from the true beginning of the tape.
Thank you. I do realise that it is 2022 and this request might be difficult to answer. I even have the instruction booklet, but the troubleshooting guide doesn’t have this as a problem .
