I didn’t face the same issue with quinto quickstart. Which quix version you are using? 1.8 or 1.7.x?
Redownload the newest quinto from your customer area https://warptheme.com/account/ , reinstall the template and let me know the result.
If possible please put your site live so I can check it directly.
NOTE: If you are using Quinto template version 1.3, go to template folder -> delete quix folder then reinstall the template. Quix 1.8.x came with new style layout so if you are using old Quinto template please update it.
