Feed problem Google merchant center. How to delete a feed for always?

[Lizenka]

Hello,
hopefully somebody can help me.
I created a feed via Marketing with Google (Prestashop module) in February that went well. Then I looked at it and the feed stopped uploading to GMC (Google Merchant Center).
I have already removed the module and disconnected GMC from Prestashop, but the moment I connect it again, the feed is still there but nothing happens on GMC.
Who has a tip?
What can I do to ensure that a good Feed is sent to GMC again?
In the image I show what I mean, you can also see the dates and that things are not going well.
Hopefully someone has an answer?
