Creating a new Motion Category is painfully slow

[latenitefilms]

Apple Feedback Assistant ID: FB13477599

DESCRIBE THE BUG:
When saving a Motion Template (in this case a Title for Final Cut Pro), creating a new Category is painfully slow. It takes a good few seconds to save a new Category - but I have no idea why?

---

TO REPRODUCE:
Create a new Title in Apple Motion 5.7, then try and save it to a new Category.

---

EXPECTED BEHAVIOUR:
It should create a new Category instantly.
