Can't publish a addon to the Edge Store

Hi! So I tried to add my extension to the Edge Addon Store, when I got this error code: 
The following checks failed:

• Package acceptance validation error: More than one manifest.json file is present in the package: hover/dist/manifest.json, hover/public/manifest.json

I tried to delete each file but didn't worked.
Can someone help me?
I uploaded it to MEGA. Link

Thanks,
