Sorry if my screenshot wasn’t clear - it is only the meant to show how to get to the invite settings - I didn’t show the right pane with the actual settings because they are likely checked differently than yours are (I was using a Meta admin screenshot). The settings are on the right side of that column and there are a few there related to invites that may apply to your case. I will have a look at this issue in more detail but I could not reproduce on my test instance.
