Clocks Timer Numpad seems useless (could just use the +/- keys)

Reproduction

1. Open Clocks
2. Go to Timer
3. Click '+', numpad pops-up to get in the way
4. can't backspace, doesn't overwrite, have to refocus, or highlight to even use the numpad (quite useless IMHO)
5. +/- would suffice for my use cases
6. Have to toggle keyboard off to go to other clocks items.

Expected behavior would be no numpad.
