Gallery only showing one column

Hi, I’m putting together a portfolio website using an existing theme. I have the gallery set to three columns and it was working fine until now. All the pictures are suddenly showing up as one column and I can’t change it. The gallery still shows up as three columns in editor. I tried the tiled gallery and that seems to be fine. Is this a glitch? How do I fix it?

So far the only thing that seems to be affecting the column gallery is changing the image display size. Full size and large shows up as one column, and when it’s medium or thumbnail it turns really weird with a bunch of columns.

Please help 🙁
