Very frequently (daily to once per week) Merkuro calendar resets the displayed calendars and i have to manually select them again from the sidebar.
This is a major inconvenience and shouldn't happen of course. 
When I select a calendar once, I want it to be displayed as long as I don't unselect it, no matter if I restart the app (or my PC) or not.

STEPS TO REPRODUCE
1. Select a calendar to be visible
2. Wait a few days
3. Open Merkuro again

OBSERVED RESULT
No calendar or a random (?)  selection of calendars is displayed anymore

EXPECTED RESULT
The calendar that I initially selected is displayed
