Yep, that's just the way Samsung handles the request for a numeric keyboard. I don't have control over that, so I added the dropdown that you can see on that dialog to switch which keyboard is used. You'll have to switch to the full keyboard to have access to the - and , keys.

Also, just to follow up, version 3.7.5 is available now which fixes the undo problem you described earlier.
