Cannot get sonarr docker-compose image to access specific volume

Expected Behavior

Should be able to access with read and write to volume S1, but keep getting the error:

Invalid request Validation failed: 
 -- Path: Folder is not writable by user abc

Current Behavior

I do get access to S2 and S3, both with the same permissions as S1. All three drives are mounted in fstab with exactly the same permissions. It's weird since I cannot access S1, but can access S2 and S3.

Steps to Reproduce

Mount drives in fstab.
Setup docker and docker-compose.
Start the containers.
Try to add S1, S2 and S3 to sonarr. Only S2 and S3 accessible.

Environment

OS: Ubuntu 22.04 CPU architecture: x86_64 How docker service was installed: Docker was installed following this guide. Docker-compose via apt.

Command used to create docker container (run/create/compose/screenshot)

docker-compose -d up

Complete docker-compose.yml. Adding fstab below too.
