Submitted URL not selected as canonical

Hey, I have never had this issue crop up before (I have been using this plugin for almost two years now) and this issue only recently appeared. I now have several of my major pages (Store directory, Leasing, contact, events page, etc) that are not being indexed because of this error.

This issue is happening on ALL of our sites that are using this plugin.
Any suggestions?

Here is a prntscrn link of what I am seeing on Google Search Console.

EDIT: Here is my environment information;

Hosting is managed by CrapDaddy (Switching to InMotion dedicated hosting soon).
