I would like to move the featured image above the post title. What code do I need to change to make that happen?

Thank you for the beautiful theme, and I am learning a lot by adjusting it to my needs.

I would like to change the meta info so that it only has the date, like: 2016.01.21

problem 1:
the date I posted on (really) and the backdated date are appearing at the same time. why is this??

problem 2:
I cannot find in the php code where the ‘Posted on’ meta code is placed?

OI am often confused and clueless, but I have looked everywhere (i think) for this

here’s a screen shot.
