Thank you for your response, Tuan.
I am trying to figure out how to reduce and/or eliminate the white space below the button and center the button (only in mobile). I was able to get the picture to disappear by using a bunch of padding codes but I think it may be a clunky way to do it?
This is what I used as a workaround:
@media only screen and (max-width: 640px) {#collection-606bf0ed9d0cb2178513ff31 .section-background {padding-bottom:150px;}}
@media only screen and (max-width: 640px) {#block-yui_3_17_2_1_1618208799104_17251{margin-bottom: -40px}}
