This is connected to your Supplier and Not updating Server with the new Layout / Setup changes from Extreme.
Not much you can do here, this is purely connected to your Suppliers Server and they can only do this there end.
Google the issue and look up the extreme Forum, you will get lost with the amount of complaints from Suppliers on Extreme along with Bugs etc..
There is a Way to do it and get it working, as server i am on is setup correct, just takes time and man power on there part to do it correctly..
Cheers
