I am experiencing the same issue. I can save the Page title and Meta Description in Yoast SEO settings for any page on the site, and I can see the data is saved in edit view, but the page source itself won’t update. I have tried purging the site cache, and have tried turning off any caching but it has not resolved the situation. If I edit the page content other any other page meta, these changes do appear on the page once saved as expected. As above, any idea what could cause this and how to resolve?
