Project Images not appearing on project site

Hi there I’m new to webflow and started working on my portfolio using the 21 day tutorial found in Webflow Uni. I’m stuck on the project image step, my images aren’t showing up after hitting "Get BG image from Projects"in the Dynamic style settings and after choosing “Project images” from the drop down. My images are in the cms and I made the image sizes 140 x 140 px or lower but it still isn’t working. Could someone please help? Thank you
