Android packaging build includes tutorial assets

I just packed the flying template for android etc1 and resulted in a gigantic size of 110MB!!! with OBB file being 83MB

when I looked at the packaging logs I found that it had cooked and put many assets that were not used especially from tutorial such as :

This is really frustrating as I didn’t used any of those assets anywhere yet they got included and made the final build fat for no reason. How am I supposed to clear these out from the packaging process.

Is there a exclude assets option like there is include assets option for cooking?
