iTunes Match with a large library on Windows 10

In the wake of Google doing a horrible job of migrating my uploaded library from Play Music to YouTube music I signed up for Match. I have a very large collection of 46K plus tracks. I turned it on to upload my collection from my laptop and Match has been going for around a week now switching back and forth between matching and uploading.

I’ve never used Match before so I don’t know if this is normal behavior or if something is wrong. What concerns me is that the “of” number (as in 3474 of 43532) never goes down. It keeps ticking upward, sometimes showing as higher than the actual number of tracks in my library. It seems like it is uploading different music, but what if it is going through the same tracks and then starting over in a loop that will never finish? Can someone tell me if this is normal? I don’t mind waiting if I know it will actually end.
