Content rows are small after publishing pages using a template


We are building a big website and are using templates for product detail pages.
Now we are running into some problems sometimes.

The problem occurs sometimes, but after filling the new page and using the template, when we publish the page all rows from that page are like really small. See example image.


The only solution how to fix this is dragging new empty rows on the left side of the content row and removing it again. Then the content shows normal again at it’s correct width.

We tried a different template and we adjusted the template, also we copied a product page that is using the same template. But without any luck.

Anyone got a idea what is going on here? !
