This is Colin from the Dynamik Beaver. The problem you’re having is not created by Beaver Builder.
It looks like you’re using the SocialPress Skin from Cobalt Apps and there seems to be a background color issue. I’ve just tried recreating your problem, but I can’t seem to get a gray background like yours on that menu bar without making it gray in Dynamik Design.
Can you check the following?
In Dynamik Design under the Nav tab, can you make sure the Main Background (6th option down) is set to “Color” with a value of #FFFFFF
In Dynamik Design under the Subnav tab, can you make sure the Main Background (4th option down this time) is set to “Color” with a value of #FFFFFF
Kelly, I just looked into this a bit more and I think the problem is more likely the Body Background color (4th option down) on the Body tab in Dynamik Design. See the image below:
