Hi @Andrew101,
This is a somewhat older post, but regardless of this, here is my small reaction.
Furthermore, this is the Dutch Community. There is also an English Community.
When you prefer English, you can also post on the English Community.
You have 3 active listings now. So I guess the problem has been solved in the meantime.
I did not experience (in the past) a change in the behavior of creating an additional listing.
Maybe you should have cleared the cache of your browser, to overcome this issue.
Success!
