Tom,
We appreciate you taking the time to help out.
It seems that minify in W3 Total Cache caused the layout change on the product page. Disabling minify made the product page layout return to normal.
However. The minification does improve the page speed significantly according to PageSpeed Insights and we would love to keep that benefit.
If you would be able to have a look at see what’s possible in regards to have the product page layout looking correct and still have the speed benefit of minifying that would be awesome ??
