The journalctl output looks good.
But, I did some effort to hide the hostname in the output with the --no-hostname argument, and you still posted a screenshot showing the hostname 
With that same journalctl command, you can check with below for warnings/errors since --boot that might be related:
sudo journalctl --full --no-hostname --catalog --priority warning --boot
Or two boots back (-2):
sudo journalctl --full --no-hostname --catalog --priority warning --boot -2
List all boots in the journals:
sudo journalctl --list-boots
EDIT: Oh you might be wondering where I get those arguments from, I use double TAB allot (Bash completion):
$ sudo journalctl --
--after-cursor --flush --no-full --sync
--all --follow --no-hostname --system
--boot --force --no-pager --unit
--case-sensitive --full --no-tail --until
--catalog --grep --output --update-catalog
--cursor --header --output-fields --user
--cursor-file --help --pager-end --user-unit
--directory --identifier --priority --utc
--disk-usage --interval --quiet --vacuum-files
--dmesg --lines --reverse --vacuum-size
--dump-catalog --list-boots --root --vacuum-time
--facility --list-catalog --rotate --verify
--field --local --setup-keys --verify-key
--fields --machine --show-cursor --version
--file --merge --since
$ sudo journalctl --priority
