Full width not working 2020

hi there,
I’m breaking my head trying to get my website to be full width. I saw from a few other forum questions that sometimes the theme is fixed to a certain width. I’m using Flash from Themegrill and I’ve tried everything from row settings, page settings, global setting etc. can you help me fix this?

Thank you, the problem was solved with the BB developers. They made some custom CSS for me and I’m extremely grateful - it did the trick beautifully!
