Hello Amplitude community

I’m facing an issue where the Page Title is not correctly assigning the corresponding page even though we do receive correct Page Viewed events for the same URL with correct Page Title.

The issue is illustrated in the screenshot below. 

You can see that for most events, the Page Title is correctly assigned but a significant number of events identifies Page Title = None.

Would you be able to identify what is the potential reason for this issue and how to solve it?

Thank you
