Cannot add rarbg as an indexer

Sonarr version (exact version): 4.0.8.1874
Mono version (if Sonarr is not running on Windows):
OS: Ubuntu server
Debug logs:
Description of issue: I have a handful of indexers to select when i want to add one. Before fully setting up my sonarr i noticed that rarbg was an option and again in the documentation. However after i set up torznab as an indexer i don’t have rarbg showing up anymore

Just a couple things to add. I am a complete noobie, if there’s anything required please let me know.

Also here’s a screenshot in regards to the issue:
