OH3 Toggle only works when the f7-Expandable-Card is opened

Hello,

I have the following problem and I hope you can help me because I just can’t find the error.
I use an expandable card, which works well in itself, but my problem is when I want to use the Toogle Switch for on / off the item is not switched but the card expands.
What am I missing? I have already pushed the switch to the top with z-index: 999 but no change.
