Reducing Image Shadow

Hi all,
I know this may be specific to the template I am using so you guys may not be able to help much, but I am designing a portfolio using a template and can’t figure out which setting in the designer affects the background shadow on the iPhone mockup. I don’t mind it I just don’t want it to make the words below it harder to read (where it says UX researcher, designer, etc). Let me know if you have any ideas how to fix this!
