I searched a lot before posting here. Hope it does not annoy anyone. I will try to be elaborate and yet be brief so to keep it clear.

I have wordpress.COM blog.
I also host about 5 more wordpress.ORG blogs.

I remember of using Jetpack once to connect the 5 self hosted wordpress with my wordpress.com account.

There were a a few more test sites and additions during the course of time.

Now find that my Dashboard on wordpress.com looking pretty messy. There is a table on Dashboard when I click on

My Blogs. There it shows me two tables. One on top that says 'My Blogs' listing my blog here on wordpress.com

There is second table below that, which says 'Linked Blogs' under which it lists all my wordpress.org sites. Including the one no longer existing or ones that I want to remove. In short I can't find a way to edit/remove unwanted entries from 'Linked Blogs' table. I have already disconnected them through Jetpack. However a few entries still remain and I wish to remove them. This is purely with an idea of cleaning up and streamlining and removing what is not essential/used.

Thank you in advance for your time to read and reply to this post.
