VST Live Pre-Release 3.0.55 is online

Since version 3.0.52 or 3.0.52 I’m experiencing the following issue:
In my project, I assigned one or more layers to the respective Song Channel in each song (so I can control the Song Channel volume with a volume pedal).
When I switch to any other song in the project, these assignments disappear in almost all songs of the project and go to the (standard) Stereo Out Channel.
I downgraded to version 3.0.51, and the problem does not occur there.
Can you please help? Thanks!
