Do you have no color on your calendar? I still have color but just discovered today that when I add a new category the color I select is not being applied when I categorize a transaction. I wonder if that is tied to your issue of no color. Seriously, the no color thing is a big deal to me too! I love this app (super glitchy sometimes on the mobile-but what a great tool and literally life-changing) but some things about it drive me nuts! The only other app I’ve found even close is Dollar Bird which has fallen apart this last year. So I tolerate the glitches and lack of some key features because I love the overall functionality of CalendarBudget.
