If you are using the hard written effects (Audio Effects-Reverb) and not a VST or DX realtime effect:
Try consolidating the track before running these effects.
To be frank, these effects haven't been updated in years. There are some lingering bugs for some people.
For me, if I use the hard write effects (which I rarely do as I prefer realtime), consolidating is a quick easy step that helps when weird things happen.

Make sure you select or highlight the whole track, then right-click and select Track-Consolidate Audio Region.

What this does is, if you have any edits or regenerated a section (or the track has audio chunk markers for any reason), this step makes the track one contiguous chunk.

I think the hard write effects sometimes have trouble when the track is in small chunks instead of one big one.
