Time on page creates duplication of pages in Looker Studio

We are running into a strange issue. In a Looker Studio report we feature a basic table containing Page title, pageviews and bounce rate. Every page appears on a single row. See screenshot.

Now we want to add time on page as a metric. This causes duplication of page titles. Every page now features on multiple rows instead of just one.

What causes this? How can this be solved?

Thank you

We’ll look into it. Probably the problem will be solved in the next release

Thank you but can you a bit more specific? “Next release” seems to be the standard answer to several things we reported yet in the end nothing seems to change.
