[bug]: Calendar Group can't select a category and uncategorized specific events

Issue Description

Say you have calendar A with all events categized as business_hours and calendar B with events without a category.
It is not posible to create a Calendar Group for selecting the category business_hours (from calendar A) and specific events from calendar B.

It can be seen in the following example, in this case calendar A is called "Business Hours Spain" and calendar B "USA Holy days":

A workaround would be to create a category for the events on calendar B, nonetheless, in my case, the calendar B is a remote iCal Calendar so it is not possible to edit the events.

This worked fine not long ago, that is, I could select a category from one calendar and specify events from a different one.

Operating Environment
