Stories appearing in reverse order in v5.3.3

Describe the bug I upgraded from 5.3.2 to 5.3.3 today and my stories were displaying in reverse order than how they are exported (using CSF).

To Reproduce

1. Write stories using CSF
2. Observe that in the nav pane on the left they are in reverse order, including subcategories

Expected behavior I would expect that the stories would be in the order that they were exported in, which is how they worked in 5.3.2.
