Clip gain caching bug

Just experiencing a very odd occurrence in Nuendo 14 (fairly new windows install: Version 14.0.20 Build 240 x64 Feb 26 2025). When I change clip gain level and play it back, no level change is audible (it plays back at previous set level). Then I delete the clip, then CTRL+Z to undo delete, and the audio levels plays back correctly at lowered level. This is a right pain - not possible to mix like this!

ChatGPT says it’s a know bug with Nuendo, but I can’t seem to find this issue when I Google anyplace? Any hints on fixing this ‘known bug’?

This is what ChatGPT says:
“Nuendo sometimes fails to refresh clip gain changes until the buffer or cache is flushed. Deleting and undoing forces the engine to reload the clip, applying the new gain.”

Do I have to live with this?

Quick update: I moved all the clips to a new track and applied needed effects again (phone call fxs for a video) and all OK - something odd happening on initial track?
