Hi. I seem to have precisely the same issue, except it is only on my posts.
It doesn’t appear on my pages.
I have deactivated all my new and old plugins. I’ve checked and unchecked the “Force Rewrite Titles”. Nothing helps.
All that I can think is that there might be some issue with my theme and that it not compatible with Yoast, which I’ll try next.
Any ideas what else it might be?
