Weirdly retitled & duplicated journal entries

I uninstalled and reinstalled Logseq in a failed attempt to get the buggy favorites to work. That didn’t get fixed.

Instead, I got a bizarre retitling and weird duplication of all of my journal entries. The original .md files retain reasonable names as does everything in the “Journals” page, but the names in the “All Pages” have gibberish at the end. What happened? And how do I prevent this from happening again?
