Every new alert checks failed to register

When creating a new checker, or duplicate a existing one, the alert check failed to enable and match any device ( it stay grey ).

Tryed updating to last version 21.10.11642 (6th October 2021), issue is the same.

Any kind of alert will fail (sensor, bgp, port, etc...).

When checking the entries, the entity PEMs display (mouseover) the right device (sensor in my case) but it fail to display the device in the device column.
