Three switches stay have the "on"status while there "off"

Hi,

I have three switches which I manage with a button on my lovelace. When I push this button the three switches are set to “off” (tv, amplifier etc.)

When I look at the switches itself in HA, they keep having the status “on”. When I put them manually to “off”, they jump right back to “on”. This only concerns the switches in HA. The actual switch stays “off”.

Anyone an idea what this causes and what to do about it?
