I just tried and it didnt work
I grabbed 4 in a folder and it gave me an error message on ALL 4 of them saying "a valid rate and state are required to add sales tax"
BUT the profile I created has nothing to do with any tax and if I grab one of them and go into it and change the profile to the one I want it works fine
So for some reason I cant bulk change them but can only change 1 at at time.
I grabbed 4 more in a different folder and the exact same error for all of them.
Grab 1 of them and it lets me change it in the listing.
