Steps to reproduce:
Precondition: several maintenances with both types (with / no data collection) are previously created

1. Open Data collection / Configuration -> Maintenance
2. Use sorting by type
3. See the displayed order for both ASC and DESC options

Result:
The order is reversed. For example, in case of ASC, - the "With data collection" is displayed on the top of the page

See screenshot:

Expected:
Sorting by type is working using alphabetical order, the "No data collection" is displayed on top of the list in case of ASC sorting by type.
