Can't Remove Old Currency Exchange Listings from Previous League (Phrecia)

Hello,
I'm experiencing a bug in the Mercenaries league. On Faustus's currency exchange tab, I still see listings (lots) from the Phrecia league, but I can't delete them. I no longer have any characters from Phrecia, and I assume it's not even possible to log into that league anymore since it's outdated.

Is there any way to remove these old listings?
Thanks in advance!
