Problem rendering from Sequencer

I’m in a sub-level using a camera actor and level sequence to kick out a cinematic, am clear on how this works, but when I RMB the sub-level I don’t see Default Streaming Method with either option to use Blueprint or Always Loaded. Predictably, on Render I get all black frames. Can anybody tell me where these options now live or if there’s a revised workflow. Thanks!

Should be this in the levels window.
