Conflicts with Autoptimize and AffiliateWP

Hi. I just updated to WP 5.5 on my staging site and I noticed that Autoptimize and AffiliateWP are no longer working correctly. I can’t clear the cache on Autoptimize and WPAffiliate won’t load the stats correctly. I’ve narrowed it down to a conflict with the Post Duplicator plugin. As soon as I disable Post Duplicator, Autoptimize and AffiliateWP work correctly. Any suggestions as to why?
