@Xnmedia I’ve fixed that up for you. The overlapping issue can be fixed following these steps for anyone else affected (it only affects squarish logos).

It was a necessary evil I’m afraid. We had to give those looking for a very high degree of control the tools they needed, this has the unfortunate side effect of messing up some older accounts now upgrading.

In any case, we can fix these issues in 2 mins, just let us know.
