Edited media shifting clips

When I open the timeline, the clips are no longer showing the correct sections of the clips I selected.  The system references the correct clip- but displays/plays a different part of the clip.  This was a final cut of this project- so the media was already exported correctly.  However, when I have gone in to make some modifications- the media does not display correctly on the timeline.  I have not moved any media around and it is in the same place for whole project.  The only thing I can attribute this to is possibly a bug on one of the beta updates.  However, it is doing the same thing when I open in PP 2023 also now.
