Remove shadow to gallery images with text

I have managed to find the fix to remove the shadow box on gallery images, but they still appear once I input a description. Is there any way to remove it for all instances? I have tried several fixes, but they always remove the shadow only when there is no text.

The page linked has to images in a gallery box, one with text, with a shadow.

If anyone has a tip on an easy plugin that can make a gallery with text like that, without a border, I’d much appreciate it. Thank you.
