Too much space between photos & text

Hi there. I have a similar problem that just ocurred after some dev work. The first line of every post is appearing in a wanky position on top of the first photo to the right. Here is an example of the error: https://wondermintkids.com/how-to-make-a-quick-easy-dairy-free-slacker-shake/

The only way I have been able to get the line from disappearing from above the photo is by pasting in this code: above the text in the editor:  

However, that solves one problem but leaves a big pad of white space between the text and photo, which I cannot seem to get rid of. Here is an example of that.

Thanks in advance.
