Any fix for a locked groove?

Hi
I recently did a large lp to cd transfer (about 150 LPs) and 5 of my records had a locked groove.Of course,most of them had a locked groove on side 2 towards the end what made it even more frustrating.I put down some notes to remember the damaged tracks in hope somebody on this forum has a remedy how to fix it.All records were produced in the 90s and were extensively cleaned on VPI machine before the transfer.Any help would be greatly appreciated.

Hi Nsgarch
good post in respect of SME V, AND RB600.
Thank you,

If my tone-arm SME V is sufficiently low set-up for VTA, some slightly warped records touch the arm close to the thick end of the arm tube when the needle is in the last 1/3 - 1/4 of the LP. This lifts the arm out of the groove with every turn and again = "locked groove".
Solution: use a higher (taller cart to go up with the arm for same VTA, use cart with more positive VTA requirement, clamp the record a bit harder to flatten it some more, if it can be done, don't play warped record, use tone arm with thinner arm tube, etc.)
