Docker: UI Service Configuration not persistent

Hi guys,

just a question. When i set the UI Service Configuration (in my case icon format -> Bitmap) and restart the docker image the setting is gone (back to vector).
Anyone knows about this ?

Updating the basicui.cfg in userdata/services folder works

Anybody have this, too ?

I can´t configure something like services, ui´s or such over paperui because next time i restart the docker it´s gone … is that normal ?
