Um... yes.
There are only two rules for the folder and it looks like the first rule is creating some sort of clash.
The first rule effectively says if Tag - contain Tags; Tag A, then add Tag B and Tag C - this works
The second rule says if Tag - contains Tag A and Tag B then move the file (Tag C is common to other files I don't want to move)
If I turn the first rule off, then the second rule matches as expected, but not with both turned on.
If I use your inspector and click on the 'i', the drop box at the top has a checkmark next to the first rule, but not the second
