admin.txt keeps clearing

[Shadowrain]

Hi I've made a dedicated server with steamcmd on another computer, everything is working fine, but trying to set admin with steam ID dissapears every time I start the server up, I open the file and the id that I've entered is blank, anyone have any ideas why the file keeps clearing?

[( ͡° o ͡°)]

Write admin id and make it read-only maybe will work
