So why does Horizon reject all names one tries to give for a new currency?

I managed to create one currency fine, then on the second one somehow it said name in use, but it turned out that it had created the currency so maybe somehow I hit the create button twice or something; but from then on I have not been able to create any currencies, as no matter what name I try to give it it claims the name is already used...

I mentioned this earlier but so far no one seems to have any idea how this could happen...
