OS is Arch LINUX

Just let me know if there's any other info you might need to track this bug: It was working properly until an update to a later systemd version (I'm not entirely sure this is the cause)

systemd 248 (248-3-arch)
Linux jarvis 5.11.11-arch1-1 #1 SMP PREEMPT Tue, 30 Mar 2021 14:10:17 +0000 x86_64 GNU/Linux

I think it was fixed here #8692
Just check it with the latest nightly build

[JonAnder83]

Yup, that fixed it. Thanks!!
