Aligning Envira Album thumbnails in a row

I created envira gallery albums, and want to place 3 of them in a row on the homepage. I tried to use shortcodes [row] [span4] [/span4] [/row] to make it happen but they appear very small. https://prnt.sc/gcvcxn you can see it in this screenshot.

Any ideas how to make them stay the size I need them to be?
