Numbers App not fuctioning right
Sometimes cloud sync can get behind. I would log in to Numbers / iCloud online and determine if you have duplicates and clean them out from the web interface on a computer browser.

At that point, you can wait for Numbers / iCloud to clear on iOS or go in using iCloud Drive app and clean out the duplicates. You may have to do this on iOS if you don't have easy access to a Mac or computer browser.
