Button appearing in odd location or not appearing

When a post is first loaded, the pin it button doesn’t appear on the first image or appears in an odd location (somewhere below and to the right side of the column the image is in) either over some text or another image but not in the proper location.

After scrolling down and back up, the button appears in the correct location.

This is happening on our staging site (https://8f6.31f.myftpupload.com) where you will also notice that the button does not appear on the main page at all.
