Memory and disk size buttons don't work with version 42

Hi there,
After the update to v42 and the change of the memory and disk size from a slider to a -/+ button it looks like they don't work reliably.
The + button only increases any of those once, and the - button is able to decrease the values but when it reaches the minimum, if you hit it again, it will reset it to the max allowed value.
I've recorded a video to show it.
