[rules-users] Guvnor - archival option

I archived a rule, then deleted it within Administration\Archive (using the "Delete selected asset" option). However, when trying to create a rule with the same name, I receive the following message: "An asset with that name already exists in the chosen package. Please use another name". I do not see the rule under Archive any longer (since it was deleted). It seems, however, to still be recognized within the repository. Anyone know how to solve this? Thanks Rob Fisher
