Widget disappears from widget carousel

Hi, I have an odd problem and not really sure where to start looking.

I have developed both a widget and an activity app (obviously using different UUIDs). I install both the app and the widget to my fenix 5. The widget appears in the carousel and works fine. However, after I have run the activity app version (which also runs fine), the widget disappears from the carousel and the only way to get it back is to restart the watch., It seems to be some sort of a "conflict" between the app and the widget but I have no clue what could be causing it. 

Both the widget and the app has settings, I use Application.Properties to read and store settings. They share the same names of the properties but since those properties are local to each app I don't see how that could be the problem. 

So, Im a bit clueless here, has anyone experienced a similar problem?

TIA
