The problem

When I create a standalone vacuum map card, everything works perfectly.
Now, I wanted to show this card only when I hit a button. So I put this same card inside a conditional card.
The card shows up and is hidden as expected when I hit the corresponding button. However, even if it shows up, it does not control the vacuum anymore.
I checked on the interface, and I can see that on the standalone card, when I select something, it appears in the "selection" field. With the card inside a conditional, the "selection" field remains empty whatever I select (in any mode, room, zone...). So I guess it is sending to my vacuum to clean...nothing and that is why it is not working.

Here is the card "alone":

And here is the same card (exactly same code) but inside a conditional:
