15.5SP5 - German WakeUp Call IVR - broken after every Update?

[Futureweb]

Hey there,
I customized Wake-Up-Call Language (to German) like noted here: https://www.3cx.com/docs/installing-hotel-pbx/#h.aujpzeq9qxjl
But after every Update the Language Files are reset back to English ... which is REALLY annoying ...
Please add some checks to Upgrade Mechanism ... or maybe seperate Directories for different Languages?
thx, bye from Austria
