Octatrack - Save Selection As Sample (but where???)

Feel like I'm taking crazy pills. I make a selection in the sample editor, click the "EDIT" button, hit enter/yes to open the menu, scroll "save selection as sample" and hit enter/yes, NAME the sample with something new, and click enter. It says "Saving sample" for less than a second, then takes me back to the sample edit screen.

Now i go to assign my new sample... and it's nowhere to be found.

For what it's worth I am editing a recorded sample that is on a flex machine.

What am I doing wrong? Where are these samples being saved??

EDIT: I am an idiot, found the samples saved into the AUDIO folder as .wavs. Feels like they should also give me the option to assign though!
