We are a system with a single listing for both Level 1 and Level 2, and all of our 'locations' (and future/placeholder locations) are Level 3.
1 - Level 1
2 - Level 2
3 - Library Name - Level 3
4 - Library Name - Level 3
5 - Library Name - Level 3

We had intentionally placed our internal services 'locations' at the end of the list so they would be less likely to be interfiled with our listed locations.

These locations seem to be sorted by digit (1, 10, 11, 12) even when its number isn't listed, not by the actual number in Gear/Settings > Library Defaults > Location Hierarchy (1, 2, 3, 4, 5) or by alphabetical order.

Requesting options to adjust location sorting in Vega Admin.
E.g., Level, omit Closed, then alphabetical (like the patron view sees)

The current sorting/order in Vega Admin slows down processing time for updating location details, such as operating hours and exceptions (closure dates).

Processing example: Since we have configured location and hours (including exceptions/closures) at the Level 3 - Branch, we must configure the exception/closures for each location. This allows branch-level versatility, such as extended closure for maintenance or construction project.
As I updated the location hours through Menu/Settings > Page Customizations > User Tools > Configure, the order in both dropdown menus for "Guest library location default" and "Choose location" seems to match the sorted-by-digit list for "Level 3 - Branch", although the numbers aren't listed.
