Manually added optimized version can't be selected

A bug is something not working as intended with the choice made. Not liking the choice does not make it a bug.

Well I suppose its a good thing this isn’t a bug report. It still presents the element of a very poor user experience.

if you want to keep a certain quality you can change it for the app as a whole. Just because because someone has multiple optimized version of different episodes does not mean those optimized versions are of the same quality. there could also be multiple versions of same or different quality of the same episode

This kind of ties into another thread on app-wide quality settings. And lo and behold the driving point for the suggestion is hardware inefficiencies. The client choice comes first, but having conflicting settings for it is an awful idea.
