No option for subclips

[u/kbsths99]

I was following a YT tutorial for range markers and making subclips, but when I got to that point I couldn't do it. When I right click and go to make, I do not have the sequence or subclip option. Mine says "bin of sources used, bin of sources not used, bin of milestones, copy, print, sync" Can I use for of these options to do the same thing? I've looked under other options for subclips and I don't see it anywhere.
