cfggameplay.json problem with enabling

[MastahBastah HNY 2018 1]

Hello, iam trying to change some settings inside the cfggameplay.json file in my server files.
On the official bohemia wiki they are telling me to enable this usage of this file inside the serverDZ.cfg file. https://community.bistudio.com/wiki/DayZ:Gameplay_Settings
I am able to find this line "enableCfgGameplayFile = 0;"
Original it is set to 0
But when i change it to 1 and start the server back up, it gets overwritten and goes back to 0

what do i do wrong?

all i want to do is get rid of the new sprint strafing left to right, cuz its so slow and i cant get used to it.

Can be closed. there was an option on nitrado web interface to enable the file, and it works now!
