Jon_Cannon_Help

Site URL: https://www.joncannon.co.uk Hello everybody! I am new here and really need some help. I am using the Jasper template. I have an issue with the secondary navigation information (in the top right of the screen), flashing very quickly in the top middle of the screen when I click a link to visit another part of the site. It happens on tablets and desk top, in both Safari and Firefox. My question is: Is there any way to stop the navigation 'Context Library' and 'About' flashing briefly out of position when I re-load the site or click on links and load different sections of my site? Thank you very much! Jon
