App loading page classes before transition's been done

I have a problem with transitions, when I click on a link to navigate to an other page it shows the classes etc before navigated to page, like a snap and then it shows the page as normal.
Am I doing something wrong? has anyone else this issue.

**For example I’m in page 2 and I want to go to page 3, when I click the link it shows the classes (cards) in page 2 like a snap (very fast) and then it goes to page 3 (all this happens in ms, but I can see it).
