Vanishing video

DCEDIT

I'm trying to tweak a clip to fix a lag in the audio, matching it up to the video correctly. The clip plays fine in VLC and the built-in Windows 10 player but it is out of sync in VideoPad 5.32.
I have unlinked the audio and video, but when I shift the audio, the video track disappeared. The same thing happens when I shift the video--the audio disappears.
I searched the forum for advice on this but didn't find anyone else asking about this particular problem.
Of course, I'm on deadline. I could really use some help.
Thanks!

That's a very dated VP version. Update to the latest. For licensed users upgrades are free for up to six months from purchase date. After that, VP will continue to fully function but a fee will be required in order to register the newest. Retain your old install file and registration info.

Right-click in the blank area of the audio track and LOCK TRACK. It cannot shift after this is done. Or lock the video track and shift the audio.

Thanks so much. I'll give that a try.
