Could it be that since 11.3 the Hierarchy: (or parents) links are not working anymore. 

In the past I used the top row with the hierarchy (showing the parents) as breadcrumb navigation.

Regression or new feature?

I tested with Chrome and Brave, same result.

just found the bug: 
OP-8772

Hello Rainer, 

Thank you very much for reporting this behavior.
The bug is fixed now. 

Kind regards
Samantha
