Hi Mike
That is odd for sure. I could see this being tricky to diagnose over a Q&A so I'll suggest some more things and ultimately you might want to try to see if someone can help.
These are just guesses / possibilities;
- Do you have any caching plugins etc? Try disabling those
- Try disabling / enabling Yoast. Your settings should remain.
- Try one by one disabling other plugins and seeing if it changes.
- Are you using a theme that could conflicting? Check your theme settings.
- You may want to try Yoast support directly - he typically will claim it's not his plugin causing an issue (and 99% of the time it isn't) - so might be tough to get help, but that would be the ultimate source I think of a solution.
Beyond getting hands on with it, that's what I could offer as some other guesses. It does sound like something possibly simple. I would keep exploring all options! If you do find the cause feel free to write back and let us know.
