Square Terminals displaying Variants incorrectly

[TimW2]

Team,

We have square terminals that aren't displaying variants correctly.  Instead of showing sizes for a product in order of S to 5XL...it shows XL as the first variant.

Further, when we have 3 variants of Small for example...Black, Camel and Orange - it is showing S, S, S/Orange.  So it's missing the full variant descriptions.  It's happening across all our Square Terminals.  Any suggestions would be welcomed!
