Sync issue with Multicam clips

I have been a loyal user of Premiere Pro, but recently, I've encountered an issue that has forced me to switch back to Final Cut. About 80% of my work involves multicam clips, and I had no problems until a few weeks ago. Now, the multicam clips I create are experiencing audio sync problems; the audio can be off by as much as 10 frames or sometimes just around 4. I have tried both Premiere Pro and the Premiere Pro beta, and both versions show the same issue. In contrast, they sync perfectly when I create multicam clips in Final Cut. I would prefer to use Premiere Pro, so if anyone can help me resolve this problem, I would greatly appreciate it.

Thank you!
