If the filesystem is unmounted cleanly each time, you won't lose anything.
The journal really comes into play in the event of a system crash.  If
Linux crashes, make sure to boot back into Linux so the filesystem can
be recovered using the journal.

I seem to remember this bug, I believe it was fixed in 5.2.1.

The workaround is to manually unmount the filesystem prior to shutting down,
but you should really update to 5.2.1.
