Different loudness when i return to snapshot

[woozl.1986]

If i create a snapshot on ardour, than change to another snapshot and come back to the previous, the loundness is completely different. I have to close ardour and restart the session, than all works normally. I made a video

Best guess: One of the plugins on that channel boosts the signal.

Does restoring the mixer-scene that you create around 16 sec into the video also restore the level?

Does bypassing (or removing) the plugins on the track help and explain this?

Thanks Robin. It was the Zl equalizer that suddenly raised the level. After a restart, everything works normally, even with the Zl Eq. Because of interest, I have now installed the older version of the Zl eq, version 0.3.5. This error does not occur with this version.
