My Aperture trash always says I have 494 versions there? How do I get a clean trash bin???

Everytime I go to empty the bin it says there are 494 versions being deleted and this cannot be undone. I empty the trash... It should be zero but...I throw one other version away... it says I still have 494 version plus one or two.... when the trash is visibly empty it says there is still.. 494 there??

How do I get this fixed and am I losing files if I empty this??
