Can you check if the extra BasicStation info has appeared in the gateway settings (menu on the left will get you there, scroll down a bit, it appears after the description box, gateway server address & required authentication):
You should expect the LNS key and the three attributes. The numbers/entries/details will not necessarily be the same.
If you can’t see any of this stuff, then delete the gateway and re-claim it.
You will not be able to reuse your gateway ID so think of another one.
PS, the public bit is optional, I turned it on because I’m a nice TTNer
