We are looking at a few of our vendors history and trying to figure out how it's possible that the account details are missing. After looking further we realize it has affected all the Vendors who were combined with Toolkit. I've attached a screen shot.

By the way, we wouldn't have required using Toolkit at all if there was a drop down menu for Report Groups in AP. Since there isn't, we use Control Accounts instead and since it's impossible to change a Control Account in AP, the only work around we've come up with is creating a new account and using Tool Kit to combine into. We've done this to dozens of accounts. Now to find out we've lost all our details in history as a result... not good!
