Disable PostGrid Post Blocks in Editor

Hi,

I like your post grid tool which is the reason why I bought the plug-in last year and for a second website yesterday. However, I dont need the plug-ins post blocks, and they are confusing my users. (Why are there two image blocks? What is the difference between the blue Post Author block and the black one?). Id like to diable them from the post editor. Thank you very much.
