your metadata is inconsistent (on the Left)
some of those are LN. FN
This one is Fn Ln and is sorted in the correct place for that.
BTW Note the RED Title sort. you may have the books Language set incorrect (sort rule to use) or it is just wrong
The Quality Check Plugin can help sort and fix the inconsistent part.
Preferences: Tweaks: has various sorting overrides (
take time to review all the tweaks,then form a plan to go with your choice)
