Bulk trades are not showing up on the site or are extremely delayed

My lisings for bulk currency are taking hours or even days to show up on the listing site, and also taking the same time to be removed afterwards.

I thought they weren't listing at all until I tried leaving one up a few days ago. The next day I suddenly got spammed for the trade because it finally listed. Then I removed the listing once the sale was finished, and I still got spammed for much longer than usual.

I just did another listing for alterations to divines and it took 15-20 minutes to list, when I suddenly got spammed. I took down my listing and now, 15 minutes later, my listing is still showing on the site and I am still getting spammed. I have changed zones multiple times.
