Guests count must be wrong

I have a subscription website using memberpress and all of my forum pages (categories, forums, topics, replies) are tested to be redirected to an unauthorized message page. Yet, I am seeing constant “guests online” and in the past 24 hours I’m showing 39 guests. This has been typical since we set up the forum.

Can you tell suggest where this guest count is coming from? I know I can hide this statistic but I’m wondering if somebody unauthorized is somehow getting into my forum.

Thanks much,
Tom
