Base // Will Marshall Script issue

Hi everyone, hope you are all doing well.

This might only be for those that actually know the Will Marshall script for Base // hopefully someone can point me into the right direction.

I have recently downgraded to Ableton 9.1.2 due to this third party script not functioning on the 9.2.2 version, and everything seems to be working fine except for the selection buttons at the top of the Base. The top row of select buttons doesnt function properly,  for instance, I can stop clips, and I can change the patterns of the drum sequencer, that's all good, but I cant select different channels.

Any idea what this could be? I have copied the script over and all checks out. Not sure why its just this now.

Thank you!
