Input number box does not work

Did not recognise when, but my input_number (box) stopped to work i.e. box is not displayed.
Slider works w/o problems, Box is not displayed at the end of line :frowning:
Does anybody else have the same issue?
I am using HomeAssistant 0.79.3

    name: Irrig watermeter adj
    min: 0

    mode: box

Uh, I see, it is discussed here
