error when using mode 2

I think this may be a bug. I got the following error message after adding a mode selector, which I did following the examples from Glenn V. in this post:

Question? I need Help Implementing my TouchOSC replica of the AKAI APC40 MK2 with abelton.

I could not get this working by having the mode selector in global mode. so i used the method above.

the error:

css_launch_control_xl_beta’ object has no attribute ‘mode_2_configs_map

I have found a solution with AI and resolved it by adding this line to the py code directly:

self.mode_2_configs_map = []

Now it works fine. But the file compile by CSS , although working would not stop giving the error

I wanted to attach the complete file for information (but it is a big project and does not let me upload it) .
