Smartthings NEW APP - Fibaro Double Switch 2 (FGS-223) - Second channel problems (child device)

Application version: 1.7.41-25 - Smartthings NEW app

I keep having issues with my Fibaro double switch 2.
While the first channel is working great, the second channel is not.

I am using the official device handlers.
The second channel, while it works when i press the on off button, the device keeps spinning on the app without properly showing that the state has changed. The loading icon can keep spinning without ever showing that the state has changed. When i exit the device and look at the device’s card, then the device’s state shows as changed. I have no idea why this is happening.

Please help me!
