Hi Yannick,
We've discussed this and think it's best for you to open a support case here:
https://www.ibm.com/mysupport/s/createrecord/NewCaseSince the configurations can be so different on containers, it was recommended that this be checked for you and they can confirm expected behavior.
If you do find that you end up with a solution here, we would love for you to come back and say how it was solved or that you have to file an enhancement request so others can vote for it.
Thanks!
