Reduce Padding Under Grid Gallery image in 7.0

Site URL: https://www.gottliebfoundation.org/painting-1920-1939

Hi! 

I'm working on a grid gallery in Squarespace 7.0 and I'm attempting to reduce the padding under each image so the captions look like they belong to the image above instead of the image below.

Can anyone help out?

Thank you!
