Priority independet of children tickets

Added by Gisela Grabe about 1 month ago

Hey!

Redmine version: 3.4.8.stable.17840
Ruby version: 2.3.1-p112 (2016-04-26) [x86_64-linux-gnu]

I have a problem with the priority of tickets. If I have a parent ticket (doesn´t metter which tracker), the priority is not changeble anymore.
Also it doesn´t change when I change the priority of its child ticket.

Under Administration - Konfiguration - Tickets, I found 3 options "Properties for major tasks". For Priority, I already choosed there "independet of subtasks".

Is this a bug or did I miss an important configuration?

Thank you a lot!
