Auralia / Musitian LTI given and surname are swapped

[savila25]

We have 2 apps called Auralia and Musitian (same provider), they recently reached out to say that our names where showing incorrectly on their side e.g.

Givename: Smith

Surname: Mary

We check all the configuration for our users and the only thing we could find was that sortable name was set to:

Smith, Mary

App Configuration is showing correctly according to them, image attached.

Any suggestions will be appreciated
