Okay, I know what was wrong! This was really an aggregation of unfortunate "coincidences"
In the last case, the Decrease_CC1 and Decrease_CC11 scripts did call the wrong function with the wrong parameters. They still referred to the increase function. I fixed the files locally, but forgot to update those in the repo.
Yesterday, I completely removed my local files and installed the repo again. So now, I had the same issue as you
But now it's fixed, please update the files and tell me if it works for you!
