I think I got it, what I did was load a figure, clothes, and shoes and saved it to figures. Then opened a new screen.  Then click on my model package-everything came up great.  Then I saved it in Pose, made a new screen and tried to extract it --nothing worked just got the delete sign same as what you had.

Bottom line, try loading your stuff in the figures portion, if that doesn't work, try props and so forth.  Jan
