Yes, you have to contact Apple to put some pressure on this issue.
It is a known issue (oversight) that, I'm sure, they must be aware of.
This happens also in other areas in Logic, for example, Custom Icons.
The problem is that in previous file systems, the system itself returned any file list in sorted order, so the app, didn't have to the sorting when it receives the list. The new APFS file system in HighSierra doesn't do that anymore (as Cuauhemoc pointed out). That means the Logic team has to update their code to now do the sorting on the receiving side inside Logic.
This is a perfect example why you always have to wait a month or two before upgrading an app or system if you have mission critical issues like that (THere are also other even more annoying issues with HighSierra and Symlinks).
Downgrading an OS is no fun, especially if you don't have a cloned backup.
Hope that helps
