Blogs Home page?

I have searched but did not find this anywhere, I am looking to edit the blocks on the blogs home page, but that is the only section of the script that is not in the page builder. there is only one blog page, why is that?

You can manage the blogs' home page through administration > builders > pages blocks > blog home. If you're using an older version of Dolphin (e.g., pre-7.0.3), it may not be available for you, in which case you'll have to update to the latest release.

I am currently using 703, but it is not there
