How to save facility permissions for users?

In Administration > Users, when select individual facilities under “Facility and warehouse permissions” or “Facility permissions” and save, the selection doesn’t appear to remain selected. What’s going on here?

Administration > Globals > Security > Enable Facility/Warehouse Permissions is supposed to “Enable Facility/Warehouse restrictions in the user administration form”. Should this relate to the above? What I do see this change is:

With this disabled, Administration > Users settings has “Facility permissions”.
With this enabled, Administration > Users settings has “Facility and warehouse permissions”

I’m confused.
