Sonarr only half skinned?

[Schmockbert]

I succesfully installed the theme in radarr, and something's working in sonarr, but it's a bit off.
I'm running letsencrypt and have modified the subdomain config files for radarr and sonarr, here's the sub_filter block from each:

# Theme proxy_set_header Accept-Encoding ""; sub_filter '</head>' '<link rel="stylesheet" type="text/css" href="https://archmonger.github.io/Blackberry-Themes/Themes/Blackberry-Shadow/radarr_in_organizr.css"></head>'; sub_filter '</body>' '<script language="javascript" src="https://archmonger.github.io/Blackberry-Themes/Extras/in_organizr_background_fix.js"></script> </body>'; sub_filter_once on;

# Theme proxy_set_header Accept-Encoding ""; sub_filter '</head>' '<link rel="stylesheet" type="text/css" href="https://archmonger.github.io/Blackberry-Themes/Themes/Blackberry-Shadow/sonarr_in_organizr.css"></head>'; sub_filter '</body>' '<script language="javascript" src="https://archmonger.github.io/Blackberry-Themes/Extras/in_organizr_background_fix.js"></script> </body>'; sub_filter_once on;

I've cleared cache, refreshed, inspected...
I can't see any error on my end, try as I might, yet this is the result:

Current Sonarr theme in the repository was designed for Sonarr V2. I haven't had time to update it to support V3.
