If you open the bag and it's window is over your inventory window the bag will just keep closing. Open the bag window and move it off to the side away from your inventory window then you can add the gems.
As for Charms just click on a charmable item to open the window. It is a bit different from DD because all the charm slots are crossed out. Does not matter, just drop a charm on any charm slot.
