Slanted instances are not properly sorted
When a variable font has ***** axis and right leaning instances (common oblique styles) the Oblique instances gets sorted before the Romans on the font menu dropdown. See attachment.
According to the OT spec, right leaning instances must use negative values, so I‘m guessing Adobe’s font menu is sorting instances by slnt coordinates in ascending direction when it should be in the other direction.
This is not only bad and uncommon for users but is also pushing font developers to make fonts against the spec just to circunvent this situation. Plase fix.
Note. All the fonts tested have proper STAT tables and axes ordering is correct.

For some reason the word "*****" was redacted on the first sentence.

For a quick testing of the issue you can use Inter variable font https://fonts.google.com/specimen/Inter?vfonly=true
And it worth to mention that Acumin Variable Concept shows the instances in correct order because the Italic instances use a positive slnt value (12) which is inconrret according to the VF spec.
