I have experienced an issue where occasionally the waypoint entry sequence ends up corrupt or with wrong INS alignment after completion. Also when in flight thus is almost always guaranteed to go haywire. It seems that there might be two issues worth looking at:
when watching the keys being pressed in the RIO cockpit, it seems that the very first point"s coordinates are not preceded by a press of the "CLEAR" key. AFAIK, this might lead to problems with data entry corruption in the F-14
it might also help for stability if there is a small pause placed after after selecting "TAC Data" on the CAP drum and before the actual coordinate entry sequence starts. I have noticed different outcomes in the F-14 depending on whether i manually pre-select TAC Data on the DRUM or deliberately leave it in another position before starting Aircraft Data Entry in the DCS WptEditor.
