I can’t see anything wrong. I’m willing to look at your project if you want/can put onto a filesharing site.
The only thing left is the object layer names or object hitbox. Are you using the most recent version of Gdevelop? they had an issue with the automatic hitbox. I’m not sure if you’re familiar with the debug action to show the hitboxes. You can try adding it. Also make sure everything is in the group.
What is this? Is this so only 1 toggle can be selected at a time? I didn’t look at it. You would need the same logic as the code that enables the interactions. Actually, you wouldn’t need interactions, so they can be disabled.

I rearranged things a bit to prevent more than 1 button from being pressed at the same time. There might be a better way but this works. It might need further testing. It’s tough to check for every scenerio.
The issue was the [inverted] on button. If more than 1 button was pressed then it wouldn’t uncheck them. I think this works for both clicking and dragging. And with the interactions being disabled, you wouldn’t need the part that enables and disables the interactions for the toggle buttons.
