I need some help setting up Bulk selling.

I am desperately trying to set up a Bulk Sale in-game for maps, but no matter what I do I can't get listings to show up on the actual trade website.

The small tutorial they provided isn't exactly helping, so any info on how I can set this up properly would be greatly appreciated.


Edit: It seems like T15 Waystones are bugged or something on the Bulk Trading site, because when I tried listing Precursor Tablets it worked without issue.
