Hi there,
Thanks for reaching out. I’ll try to help with your issue if I can.
Looking at how this works, I can see why they chose to solve the problem of concurrent events that way, but I agree that it looks confusing. Unfortunately, I’m not sure I have any quick suggestions on how this could be implemented differently. If you have a solution that you’d like to try, I could offer some tips on identifying the elements you would like to modify with CSS.
You could also make a suggestion in our User Voice forum, though that’s not going to be much help in short term.
Sorry I don’t have a better answer for you! If you have any specific questions about customizing the calendar styles, please let me know.
Thanks,
Sky
