FIBARO Roller Shutter V3

[Knibor]

Hi, i have a problem with the FIBARO Roller Shutter V3.
When the roller shutter is open and I close the roller shutter with the device "roller shutter" switch, the notification from the device goes from "open" to "close" after the roller shutter is closed. But when i open the roller shutter with the device "roller shutter" the notification from the device stay on "close" after the roller shutter is opened.

The roller shutter is a type "roller blind", so there are no end switches to detect "open" or "close". Domoticz hardware setting of the roller shutter is "Roller Blind"
The Fibaro roller shutter is only connected with Domoticz and there is no external roller shutter switch mounted.

I run on Domoticz stable V4.10717 with Rasp pi 3b

Thanks
