Why does the Content Optimizer not recognize singulars vs. plurals?

We understand that it can be frustrating when the Content Optimizer doesn't work the way you want it to! We've mulled over how to get the Content Optimizer to recognize the singulars and plurals, and don't have a solution because sometimes it could change the meaning of the word or the word. Definite room for improvement by us.

Instead, what you could do is copy the word that is not getting checked off and paste it at the top of your draft (or anywhere, but at the top you can remember to delete easily). Then, it will get checked off the list while still being grammatically correct in the body of your post.
