Error with Ultimate Branding "Visible Color Schemes"

Hello, I'm receiving the following error with the Ultimate Branding Plugin for the Visible Color Schemes section:

Warning: Invalid argument supplied for foreach() in /home/hoopsinstitute/public_html/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/ultimate-color-schemes-files/global-options.php on line 21

Can this be resolved? I've tried deleting the plugin and reinstalling but didn't work. If I can have help fixing this issue it would be greatly appreciated, thanks in advance!
