We’re aware of an issue where custom values set in Bounce Launch Value and Forward Launch Value revert to default in v36.20.
A fix is on the way, which should restore bouncers that existed when 36.20 released to their pre-36.20 values. Bouncers that have been modified in 36.20 will not be affected.
Creators can manually re-edit these options in 36.20 to try to match pre-36.20 behavior or wait for the fix to restore it in 36.30.
