Can you repeat the problem? If so, what are the steps?
I have a file with 5 video tracks. On one track I use 4 different filters, like size and mask. On the timeline around at 23 minutes the track’s filters are not applied anymore. It is in a middle of a cut.
At one frame they are ok, and at the next they dissappear.
