If the issue does not appear on browserleaks.com, but appears on some other website, that website is likely using IP-based or some other form of geolocation. Location Guard is not supposed to protect against other types of geolocation.
Include concrete steps to reproduce the issue
This is the most important information for fixing the problem:
Go to ... fixed location
Click on ... Zoom out all the way and then zoom in 4x (at least). Play around with zoom, but display will show London's name as 'Allahu Akbar' and Paris's name as 'Penis'. Zooming in 11-12x exposes the issue in more detail.
