Analog Four/Keys OS 1.40A: bug reports

Hi guys, A4 mk1 user here. I found out a bug, perhaps. When I copy a sound from a track and paste it into a track of a different pattern, the level of chorus, delay and reverb regulates the track volume. I need to have at least one of the three effects not at 0 level to hear the sound. I downgraded to 1.40 and 1.35 and the strange behavior remained. I reported it to Elektron support. Any of you have experienced the same?
