check my multisite setup 1 too many sites?

Hi there -

My marketplace setup seems to be screwed up.
It seems to have installed one too many marketplaces.

I am trying to do an Etsy-style multisite with a main portal and numerous additional sites.

I used the instructions here:

But I have a shop in the main dashboard AND in the My Sites dropdown?

Could someone check this and tell me what I need to do to fix it?
