I can't help much here, nothing to compare. I forgot to mention that md
driver is compiled in the kernel in my case.

perhaps set to true and see what it says.

.. and I assume you double checked (blkid) the UUID.

No idea - just trying to help as it sounded similar to what I've
experienced. However in your case the "--write-journal=/dev/sde1" seems to
cause the issue.
According the docs [1,2] I overflew it is used only when creating an array.
[3] says explicitly create, build or grow. For manage you should
use --add-journal
