Multiple assets

hello and good eve.
i made a mistake making 2 identicals collection from "series (multiple) " in the create menu
is it possible for me to delete them all from my contract ?
i also have no idea how to do it ill be preciate if you can you help me step by step this is so fraustrating for me .

gm! Sorry to hear that - Have these Series both been minted to a mainnet? Can you provide us a link to the series/contract you’re looking to delete?

If the token has been minted, they will need to be burned to ‘delete’ them.
