Tabs do not stay closed

Apologies for the long delay in responding. I often work offsite and away from my machine.
Here are two screen recordings from this morning. The first string of tabs includes some that have been recurring for over a month now. Some are newer tabs. I closed a few of these tabs in the recording, stopped recording and went about my work. Later they popped up again in the sidebar, so I quit Orion, started a new screen recording and re-opened it. There you'll see some, not all of the previously closed tabs. Interestingly, they are in a different order as well. This is not something that was happening previously.
