Some Comments not showing

Hi,

I noticed that some of my comments are not showing, specifically replys within replys.

On this page you can find a comment by Malte Maier from 12.08.2020, which is a reply to Alexander Dickbauer’s comment. The author Sandra Beutlhauser replied to Malte Maier’s reply but it does not show up.

Only when I deactivate the Load More Plugin, the comment shows up. I tried it on several other pages as well.

Can you help me out on this one?

Thanks and best regards,
Michael
