Current position of roller shutter (Shelly2.5) stopped to synchronize + current status is wrong
Hi,
I'm using a Shelly 2.5 to controll my roller shutter. Currently the Home App is displaying a false current state (Screenshot 1). The roller shutter is stopped, however the Home App still thinks it's moving ("opening"/"closing" instead of "open"/"closed" or "stop"). 

Further the current position is set to 30% (true position would be 100% in the screenshot 2 example). This is comlicated if used in Shortcuts for example or if you ask Siri. I provided a second screenshot for that (from the eve app as its easier to see). For comparison I provide a third screenshot from the Shelly app. I tried my best to solve this issue, however I couldn't find the cause for it, as it's always right in the Shelly app and using HomeKit it still acts as it should as long you don't use the "current position" data in any shortcuts.

I use the latest firmware and plugin.

Thanks!
