I had the same problem that was outlined in these two earlier posts:
SEO by Yoast conflict with Fitlers & Columns
Advanced Post Manager not working
which was that the “Filters & Columns” feature added by Advanced Post Manager wasn’t working — the filter wasn’t working. Searching “Title” for some text that I knew some events had wasn’t actually filtering them.
I tried the same fix that worked for John and BJ, and it worked instantly for me as well. (I would have added my comment to those threads, but they are both closed).
That fix is to turn off the Yoast feature called the “Text Link Counter” , which can be find in Yoast SEO > Dashboard > Features. It was enabled by default.
