When adding an event to the calendar, I set the event category and change the color, but as you can see in the image, when I select the event category (topic), all of them are checked.
It works fine for blog topics, but once I select one, the others become unselectable.
Is this possible to fix this so that I don’t accidentally select two items?
Is this a bug?
Thank you for your advice.
