Soft rejection and global variable

I just got a soft rejection with the message below.

global variable should be used restrictively and only if theme really needs to. It’s highly recommended not to use them at all just to keep things out of the global namespace, they’re poor coding practice.

I only use global variables to get admin options from Redux framework. For example, I have global $mondo_admin_data; in header.php file to get navbar style. I think it might be the reason. Has anyone ever dealt with this issue?

Here’s another author with similar issue: How to fix a WordPress theme soft reject Issues?

Yep, it’s exactly the same issue as mine. Thanks for pointing me out.
