strange Solver traces

How does one find and delete traces of of Solver data?

I use Solver frequently. A few days ago I decided to consolidate my primary workbook (which has about 200,000 cells) in hopes of making it more efficient for Solver.

So I did a "cut/paste" in which I removed my solver "input cells" (the variables which Solver will use in its operation) and pasted them into an empty area of another worksheet.

I knew of course that I'd need to re-enter the constraints etc. in Solver after doing this. But when I input some constraints, Solver somehow over-wrote my formulas with its own code. Here's a screenshot of what it did. Note the last two rows and you'll see the unexpected code:

I deleted the code, re-entered the constraints as usual, but again, Solver changed my entries to this code. So I took a number of additional steps including:

- Doing a "reset" of Solver to clear everything from it's interface.
- Deleting Solver from add-ins
- Rebooting my computer
- Saving as different file
- Doing an "Online Repair" of Office 365

In all cases, Solver continued to insert the code (which prompts an error message when trying to solve).

So... does anyone know where Solver data is hidden, how to access it, clean it up? Copying/Pasting the entire workbook would be the very last step for me, as I'm afraid that this is going to require that I search for and replace hundreds of parts of formulas which refer back to the original workbook.

Thanks for your help... and Moderators, if I should repost this in a sub-forum elsewhere I'll do so.
