BUG? Manualy setting buddy-size starting with 1.

Hey guys
i had a couple of led stripes today running on Roadhog4 (1.1.3 (b352)) an wanted to change the buddy-size manualy.

Tapping on the up-arrow/down-arrow in the buddy-size tile lets you enter a number.

I recognized that values beginning with 1 (e.g. 100, 10, 1) are not possible to set.
I did check with 2 - 9 what worked properly, so i guess thats a bug.

Regards
jay
