No "Only Server Matches" option in OpenAI Settings

Player Version#:4.12.4
Hello,

I’ve just configured Plexamp with my OpenAI key and that’s working, but in the settings I have no “Only Server Matches” configuration option.

So for any playlists I generate none of the tracks are found because they are not in my personal library.

Is there anything I’m missing? How can I restrict to just my library?

Thanks in advance for any help anyone can provide!
