Issue with Query using WP Sheet Editor

I’m running a site with 90K users, using MemberPress. I’m currently using WP Sheet Editors (https://wpsheeteditor.com/extensions/edit-users-spreadsheet/) to manage the users.

After using Index WP Users For Speed, notice that whenever I perform searching using WP Sheet Editors, it will always return inaccurate result. E.g, search based on specifically 1 Mobile Number, it should return only 1 result. Instead, it return all 90K.

I have check with the WP Sheet Editors developers, that’s what’s they claimed:

we make the correct database query for the search, Index WP Users For Speed is intercepting and changing our database query. We can’t do anything about that because it’s external code. Index WP Users For Speed are intercepting all the database queries, even queries made by other plugins or WP itself.
