Minor - UI - Work order condition freq.

[anjenpai]

Bug:
    when changing the condition frequency of a work order (either from the workshop or 
    the manager), the frequency iterates through the options continuously
Expected behavior:
    each press of the buttons ( - ) / ( = ) should change the frequency only once
Replication:
    (j)ob -> (m)anager -> (q) make a new order of anything -> (c)onditions -> ( - ) / ( = ) freq.
OR
    (q) -> go to a workshop -> (P)rofile -> (->) change menu to work orders -> 
     -> same as above (q) -> (c) -> ( - ) / ( = ) 

Workaround:
    disable multiplex ( \ ) -even while in the menu- before changing frequencies, set desired freq, re-enable
