Thank you for your feedback.
This type of inventory is brand new feature, just implemented. This is one of the "minor" issues that were overlooked.. Help screen is also missing remaps I have introduced not so long ago. Thanks for pointing it up. Same for character screen, it is remapped to '#' (and has some rendering problem also, as I saw), but it will be put back to '@' in next minor release.
Removing Cursed shield is a bug unfortunately. Need to look deeper into it.
I hope I can fix these really fast, and release one fix to this release.
