[Закрытые] I've often problem to see the updates on live pages

Background of the issue:
I am trying to update a page on my site скрытая ссылка. I modified the page скрытая ссылка and refreshed the translation using WPML. I also cleared the cache on both the server and browser.

Symptoms:
I see the correct translation on the live page, but the wrong image still appears in the banner. The correct image only shows in incognito mode.

Questions:
Why does the correct image only appear in incognito mode?
How can I ensure the correct image appears on the live page without using incognito mode?

I've already cleaned the cache, both browser and server side without result.
I need a solution to make these changes easier because this way every little edit requires a lot of time to be really live.
