Thanks for telling us your solution! This may help others coming here with the same problem in the future!
Still, wenn posting again on a forum, please consider more kindness to the ones trying to help you. I think all the answers to your problem gave a lot of sense and were helpful. And thoroughly listening and considering the correctness and helpfulness of the answers might have helped you to find the solution earlier… (e.g. that it was a Murena OS setting and asking on the Murena forum might have helped).
