Hi, I’m a beginner at Amplitude

I would like to ask about the event “Page Viewed” provided basically.

I have an issue in the ‘Page Viewed’ event property - ‘Page Title’.

When I move the page, some page titles are lagged, for example, when I click page A and then move to B, the page location is changed from A to B but the page title represents the title of A page.

In the source code, the title of the page is B.

Is there anybody who has a problem like this? 

I found out it is okay when every page has its own path.
