Filtering help please

Hi All

If I'm just wanting a browse rather than looking for something
specific I currently use:
get_iplayer --type=tv --long
However I want to omit audiodescribed and signed, I have tried:
get_iplayer --type=tv --long --exclude-category=-audiodescribed
But this has no effect, I'm sure I'm missing something obvious but I
can't see it.

Any suggestions?
