Avatar Imports in T-pose

I am trying to import my model as a S15 avatar and the model imports in T-pose. I used the S15-Lola from Skinning | Avatar Evolution as a template, and that model imports fine even though it is also in T-pose, it imports to I-pose in-game once you put it as a startercharacter. I am pretty new to modeling so any help would be appreciated.

If you need to see the model to help, please DM me.

Looks like a problem with the attachments - they aren’t importing with the correct positions
