Can’t complete Rey’s ultimate

I’m working in the galactic legend journey for Rey, it says I’ve completed the journey however I only have 9/10 ability mat ultimates. The game won’t allow me to receive any more rewards. Please help as this is my first galactic legend, I’ve spent a decent amount of time and money working on this unit!!!

I haven’t started any other GL journeys, and have no other way to get an ability mat ultimate
