P: Non-alphabetical order of external editing presets (macOS High Sierra)

I have quite a few Lightroom external editing presets. These were always displayed in alphabetical order in the "Edit In" dialogue box but I noticed that, post upgrade to Mac OS High Sierra, the order seems to have become random. I tried deleting and re-creating but the issue persists. Not the most serious problem in the world but a workflow nuisance. I have reverted to the previous OS with the hope that a later release from either Abobe or Apple will address the issue.
