[V1-16] S & F calculator not working on Linux (solved in V1 RC1)

[Dragonfly]

At least on my PC the Feed & Speed calculator from the MOP dropdown menu does not work. I can enter values in the fields but there's no action (nothing changes) when a button is clicked.
Ubuntu (Mate desktop) 16.04 LTS 64 bit
Today there was a complete update of Mono from 5.12 to 5.14 but still the same behavior.
