How to change admin password for Flowable UI

I’m struggling to change the admin credentials for the Flowable UI. Running the app like this:

docker run -e flowable.idm.app.admin.user-id=acme_user -e flowable.idm.app.admin.password=acme_password -e flowable.common.app.idm-admin.user=acme_user -e flowable.common.app.idm-admin.password=acme_password -e logging.level.org.apache.http=DEBUG -p8080:8080 --name flowable-ui flowable/flowable-ui:6.7.1

I can login, but when navigating to Admin app > Process engine I get error. Looking at the log it tries to call itself with the default credentials admin:test and gets 401:

The same problem occurs also when starting the app with default credentials and then changing the password from the IDM app.
