Adding ads before every Nth H3 paragraph and starting from 3rd H3 paragraph

Hello I am currently using the SheMedia plugin (boomerang ads you can see in the code) but I am trying to switch to manually placing ads with Ad Inserter (it shows as <!– BLOGHER ADS Begin 300×250 ad –> in Console).

I have been trying to add ads before my H3 headers. The general layout of my site and where I want to include my ads is:

Header 2

Header 3
Paragraph
Paragraph

Header 3
Paragraph
Paragraph

AD

And then repeat.

I have tried using %2@3 but it only works for the first ad space. The other ad spaces don’t show the ad image but show the code in the Console.

How can I fix this problem?

I enabled remote debugging and disabled caching.

This is the code that I am trying to plug in:
