Nested buttons showing with white background

Ambient

I have hunted my style-sheets and even made several changes to buttons.dataTables.css (to no avail). Can anyone point me in the right direction please. I cannot figure out why this is happening. My code is a mixture of Javascript, PHP and is reams long that's why I can't post. This white background is really annoying.

Unfortunately a screenshot is virtually impossible to debug styling issues. This example doesn't have the white space issue.

It could be you aren't using the correct styling libraries for the style framework you are using. Use the Download Builder to get the proper files. If you have the correct files then there is a conflict somewhere. Maybe you can right click on the above screenshot and use the browser's inspect tool to see what styling is applied and potentially find the conflict.

Can you build a test case that shows the issue? The actual data doesn't matter its more about the environment.
