I have problems with submitting my project to Marketplace

Hello, i trying to submit my project on marketplace but when i first time try to submit it i got the mail from Unreal Engine Marketplace and they write me

“- Product contains blueprint and code assets. If this is to be a code based product please make it a Code Plugin, otherwise, please remove the code.”

and i try to submit it as a Code Plugin but then i go another mail

"- Submission not in correct format. Product was submitted as a Code Plugin but only contains Blueprints. This should be submitted under the Blueprint category and the assets should be imported into Unreal Engine and submitted as an Unreal Engine Project. This should include a .uproject file, a Config folder, and a Content folder. If you would like to import these assets into Unreal Engine and resubmit them in the required format, we will be glad to review it.

And i dont know what to do now.
