RoonBridge process names

Naming processes started by RoonBridge script does not work. Processes that should be named RoonBridge and RAATServer have name: ‘mono-sgen’.
I see in RoonBridge startup script that it tries to name the process by using exec -a but in the end it does not work.
I installed RoonBridge via installation script on archlinux, kernel 4.18.1.
