Home screen pages disappearing (NOT hidden)

I recently reorganized my home screen a few days ago to use 4 pages. The very next day, the 3rd page was missing. I remade the page, and then a few hours later it reappeared by itself so I now had 5 pages. I deleted one of the duplicates, but then two days later the 1st page is now missing. I tried checking to see if I had accidentally hidden it, but it’s just not there anymore.

Needless to say, I can’t really use a phone that keeps having whole home pages come and go as they please. What is causing this and how do I fix it?
