That's strange. When I click on "Page Titles", I get the title of the page and not any URL.
This looks like an "expected behaviour" as we "archive/persist" the full recorded URL at the time of the tracking request was made. There is no such feature yet to change URL's in the past. This could be solved with a custom plugin that let's rewrite URLs saved in the row's metadata. I'll mark it as an enhancement as I wouldn't say it is a bug as to solve this there would be rather a new feature instead of changing this behaviour
(renamed issue for clarity)
