When you change the city on the site, the links do not change city manager opencart?

Question

opencart

there is a website, there is a city manager module. the city is defined normally. but if a person is in Tyumen, he has the contact details of the site (telephone, addresses, map, etc.) in Tyumen, if the same person puts St. Petersburg, then the site data (telephone, addresses, map, etc.) remain as in Tyumen. if you turn off caching, then the site takes an incredibly long time to load = does not cook. can anyone come across. please suggest how to solve the problem
