Hi, good that I found this topic. For me, the problem is the same, the plug, for my taste, carries out nasty practices. I have already given an appropriate rating and am waiting for approval by the moderator. There you will be able to read about this problem.
This plugin after 3 years, on two sites, created over 100,000 pages with a 404 error, a few of them went to google console. I never knew where it came from until today
Uninstall it immediately!
