Debutify theme - why does the bar overlap the search field on mobile when I select top sticky display? (ECB)

If you're using the Debutify theme and have selected the top sticky display option in the Email Collection Bar app, the bar might overlap your search field when viewed on a mobile device.  

You will need to enable sticky headers to fix this issue.  

To enable the sticky headers, please go to Theme settings > Advanced settings > Enable sticky header
