I have been meaning to post this but it has slipped my mind untill now.

The reoccuring event symbol is two arrows in a circle.

When I switch to dark (black) background the reocuring events, that has an category, symbol become not visible (black symbol on black background).

However if the reocuring event has no category the symbol is black if I chooce light (white) background but change color to grey when I switch to the dark background.

So please change so that events with an category behave like events without an category.
