Theme Conflict

I am trying to add a video to show up both an individual product page, and for it to show up on a composite product page. The issue right now is that on the composite page, it shows up SO BIG – way too big. But if you resize it using code, the code shows up on the individual product page. I submitted the ticket to the composite plugin people, and this is what they are saying:

In this case, it might be possible that there is a theme conflict which is preventing it from showing correctly. Looking over your Status Report I do see several theme overrides to the Product area, including two out of date theme options that do cover the content area of the product:

HighendWP/woocommerce/content-product.php
version 3.0.0 is out of date. The core version is 3.6.0
HighendWP-child/woocommerce/content-single-product.php version 3.0.0 is out of date. The core version is 3.6.0

Can you help?
