Steps to reproduce:

Version: TB68 integrated
I assigned categories to calendar entries. When a color is assigned to the entry, the color is no longer displayed on the right edge of the entry but it fills the entry completely. Entry text is no longer readable. When the category is removed, the calendar color reappears and the entry text can be read as usual.

Actual results:

See above

Expected results:

The category color should appear on the right edge of the entry.

Also running into this problem.
