InDesign won't change "Save As" automatic location after update

I just updated to ID 2021 this morning after experiencing bugs with the previous version. I'm noticing a new issue, now that ID is considering all older documents an outdated form that needs converted. When I go to Save As on any document that isn't already in this 2021 format, ID keeps defaulting back to the first folder I saved a 2021 ID style file in. It will not update the Save As location unless I open and Save As a file already formatted as 2021. It's not pulling up the locations for anything in any other format, which is obviously every project I've worked on before this morning. I'm being constantly routed to an unrelated folder and have to sort through my servers for the appropriate location every time I pull up a file. Is there any way to have it remember where a document is pulling from and move the Save As to there? Any plans for it to do so? I remember some hiccups with this in previous versions, but not this bad.

Project order/issue, in case it helps clarify what I'm experiencing:

• Opened v2020 file A from folder A.
  InDesign makes me Save As to a 2021 version and find a folder.
• Opened v2020 file B from folder B.
  InDesign makes me Save As and defaults to folder A.
• Opened v2020 file C from folder C.
  InDesign Save As defaults to folder A again despite working on/saving file B in 2021 format.
• Opened v2020 file D from folder D.
  InDesign Save As defaults to folder A again despite working on/saving files B & C in 2021 format.
• Opened v2021 file B from folder B.
  Selecting Save As defaults to Folder B, and now Save As consistently defaults to folder B for everything instead.
