Problems creating a bug tracker report

Hello, when I try to create a report in the bug tracker there's an option to choose a lvl 10+ character, I got 7 lvl 80 and the list is empty preventing me to create a report

Yes I was logged in and, yes I chose the wotlk expansion option and yes I chose a category too, since the link is optional I didn't bither with it, do I have to submit an screenshot to make it work or something?

Thanks in advance

For the time being only Lordaeron characters can report WOTLK bugs. That is because it was the only realm with the new core.
In the next few days Deathwing and Ragnaros will be able to report them too since they are now being upgraded to new core.
