It seems like most of those issues are caused by custom Yellow Pencil Pro modifications for that pages. Can you please disable the plugin for a moment and test if the issue will be fixed?
I tried to turn it off, and yeah… it seems the culprit is yellow pencil plugin. After i turn off yellow pencil, the image lay out turn into 66,67% for the featured image and 33,33% for portfolio description.
I tried to add additional css to set the layout to my desire, but i wonder if there is a better way to do it?
At the moment there isn’t options for that. If the changes that you would like to make are simple, then we can create a simple CSS snippet that shouldn’t cause issues like that.
