Tools are not available for custom mode

Where does the bug appear (feature/product)?

Describe the Bug

I’m not sure if its related to Composer 1 model but I wanted to add custom mode and:

  1. I’m not able to deselect “Composer 1” from models in this custom mode.
  2. For some reason even though I have all tools selected agent is not able to use them.
  3. I’m not able to change icon of the custom mode. Nothing happens when I click on icon.

Steps to Reproduce

Create custom mode and try those things as described above.

Expected Behavior

It was working properly before.
