I have a question – Pinterest Review

I’ve had Pinterest for a good while now. Love the app and all. But this just started happening Why am I seeing the save button say saved on pins I’ve never save plus they don’t show up in any of my things like all pins or other boards. I changed my password just in case but still is doing it. It just started today. Is it a small glitch or something more
