Tag Already Exist But can't find it,

hi guys,

i’m trying to a new tag on my post, but the slug url is not right, for example i used tag apple but its url is mydomain.com/tag/apple-2. I tried to find on the list of my tags but i didn’t find any apple that i created first.

However i used a xml file to import demo data. could please help how to remove that tag that doesn’t exist?
