Folder location 'stuck' in Advanced Search settings

I use Acrobat Reader on my iMac almost daily, to frequently search the same set of thousands of PDFs across hundreds of folders. It's essentially the same search that I initiate over and over, just looking for different content in PDFs located in many different folders. I use "Advanced Search" and the "Look In" field to define the search criteria and location. However, one of the many folders I've searched in the past always appears in the list. I assume this is supposed to serve a 'recently searched' purpose, as there are either two or three folder locations appearing in the list at any given time. Two of the three listed folders will cycle in and out of the list as I continue searching through other folders, but this one specific folder just stubbornly stays there, despite me not having searched that location for a year or more. Not just that, but when I use the "Browse for Location" function to locate the actual folder I need to search, once I select it Acrobat flicks back to the "Advanced Search" screen and the "Look In" field immediately goes back to that one pesky folder that won't go away, and not the one that I literally just selected to browse. So I have to manually select "Look In" again and click the folder that I just selected, which will be sitting there in the list right above the one that won't go away, before I can hit "Search". I hope this is making sense. Has anyone else experienced this? Does anyone know how I can clear the search history or do something to get rid of this infrequently accessed folder from the list? 

If it's relevant I'm using Acrobat Reader version 2022.003.20314 on an iMac running Mac OS Ventura 13.1. This issue has been happening for at least two years though, and hasn't resulted from any recent Mac OS changes.

Any ideas or guidance will be greatly appreciated!

Cheers,

Matt
