What you were expecting to happen, and what actually happened?
I fought a battle in the dungeon, and I expected to get the gold mentioned on the end-of-battle summary. Instead, nada. Souls do add correctly, by the way.
What are the steps to make it happen again?
Fight in the dungeon. This behavior persists after a restart.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
None myself, but this is easy enough to check that I imagine someone will come along with pictorial proof. Or the devs can log onto their player accounts and try themselves.
