Cubase 13 retrospective recording is greyed out

im having an odd issue in cubase 13 pro. Retrospective recording is greyed out and I cant use it. Sometimes its (randomly) not, other time it is. I have a large recording buffer size and the track is record enabled AND its midi. This was working ok, now its not, have no clue as to why. Is this a new bug in cubase 13 ? has anyone else experienced this ? Is there a fix/workaround ?
