I ended up creating a workaround for this issuee.
I found out that it is just the main event calendar/list that doesn’t work, but event categories work. So I made a “Mother” category that every single event has to go under, then subcategories under that. I now simply link to that on my nav menu. I never link to the main event calendar.
I looked around a lot of forums and it seems that this issue is quite widespread.
