"References" and "Tagged Rem" from the bottom of the page are missing!

My “References” and “Tagged Rem” have disappeared from the bottom of a page! How do I get them back??

I use a tag called “quote” to tag quotes I want to remember (and I have many) - and I’ve just noticed when I go to the page for it… there’s nothing there except a “Find Text References” section - I don’t know what’s happened to the reference section and tag section! And they’re the ones I want…

Also, another strange thing about my “quote” page is that it thinks I can merge it with another… but it doesn’t work! I think I’ve previously merged it with a duplicate “quote” page - but the merge option is still there - when I click it, nothing happens. Perhaps that has something to do with the problem??
