Hi Andrew, thank you for reply.
For now I can share screenshots that I hope will help reproduce this issue.
They can be downloaded in the link from first post.
Volume reverb settings are the same (fade and volume) expect reverb settings. But they can be found in another screenshots.
What about sounds - no matter what sounds is placed inside, issue occurs on any sound I put in (when crossing from one reverb to another).
Location isn’t relevant also, I just pick up place from audio file.
