deleting multiple swatches?

hi, i hope i'm posting in the correct forum and apologies if not! (if not, if someone could tell me where this would be more appropriate i'd really appreciate it!)

is there a way to delete multiple swatches (colors/patterns) of a package at the same time? i've tried clicking shift and selecting several swatches, and i've also tried ctrl. while those select several swatches, when i click delete it only deletes the first one

thanks for any help!
