Customizr images after update

Hi,

After the last Customizr update the image headers on my post pages have a white space above the image instead of being full height. It seems to only be on selected pages however and I have tried uploading the image again.

Here is a post page which shows the roughly a centimtre of space.

This post however is fine:

The problem is roughly affecting around half of all posts. Any ideas would be very helpfull.
