Row-gap should be 7px but mine is closer to 70px

Love your snippet! It's transformational for obsidian and I hope they include it in the core. One problem - the "Grid Gap" -- column-gap is fine at 7px, but the row-gap should be 7px but mine is closer to 70px. I've tried adjusting it but it stays the same. I've only got one line between the image links, ie:
![[walker.jpg]]
![[walker.jpg]]
![[walker.jpg]]

![[walker.jpg]]
![[walker.jpg]]

Any ideas?
