Meeting invites only showing in sidebar

I have multiple Google and Outlook accounts that I’m using within eM Client. I have a meeting scheduled at 2pm today (it’s a meeting invite someone sent me that I accepted). It is showing on my Google calendar in my browser. It is ALSO showing in my Calendar on the sidebar. But it’s NOT showing in my main calendar view even though I have made sure the correct calendar is checked on the left sidebar.

This ONLY seems to happen when it’s an even invite from someone else to me.

Here is a screenshot that shows what I mean.
