When downloading, the bitrate is provided by the streamer, so you usually get some random numbers like 2386kbps. When encoding, the bitrate is provided by Streamfab, so you get whole numbers like 15000kbps, 8000kbps, etc.
Anyway, the episodes in question still won't download in 1080p, even though it was offered in parsing. Some other movies I tried also would only download in lower resolution. Looks like whatever titles, even older ones, that would not download before is still not downloadalbe, at least in HD

That is categorically false. The round numbers are just labels and not the actual bitrate. We lobbied StreamFab to give us real approximate bitrates and it has been like that since v6.1.3.6 that was released 2023-08-24

IF you are seeing round numbers, my guess would be StreamFab cannot access that video or you are using a Codec and Bitrate type that is not available.
Please provide us with the details of the media you are trying to download that gives you these round numbers so we can see for ourselves.
As for the dropdown showing you that it is available in 1080p so why can't it download it, that is because the MPD file contains all that info and you do not need decryption keys to read that info. It's just an XML file. So just because it shows you it is available in 1080p, it won't download it at that resolution if StreamFab can't get the keys for it.
