[BUG] Unraid file owner/permissions not correct

[azuretower]

Prerequisites

Please check the following before continuing:

• [X ] I have searched for existing issues, including closed issues to ensure this is not a duplicate.
• [X ] I am running the latest version (See latest release)

Environment

• OS: Unraid
• Type Docker

Description

I have installed the program using docker on Unraid with the template from Community Apps.. It has the environment variables:
PUID: 99
GUID: 100
UMASK: 022
These don't seem to be working correctly.
Files are saved as user "root" instead of "nobody" as would be expected for PUID: 99

Expected Behavior

files should be owned by the "nobody" user

Actual Behavior

files are owned by the "root" user

Additional Context

I also tried adding "--user 99:100" to the extra parameters section in the docker template. That made the program unable to start. The container will not run with that parameter.
