Trade Listing for beasts does not work

Dear all

I noticed following issue:

I'm in a group of friends and we lately discovered beast farming. In the end of each run we collect all beasts and I put them in Public Stashtab to get them visible for trade.

Issue is: My beasts get never listed and I have no idea why.

When I put a single beast (lets say an expensive craicic chimeral) into another stashtab (~2c b/o) it gets listed immediately and people whisper me for the beast.
If I put them into an individual priced stashtab or into a another default priced stash tab (lets say 30c b/o) they are not shown.

I tried different stashtabs and different settings and have no idea what the issue is.

Anyone experienced the same and could help?
