Steps to reproduce:

1. Configuration -> Maintenance -> Create maintenance Period
2. Maintenance Type: With data collection
3. Active from 2023-11-01 00:00 until 2023-11-02 00:00
4. Period: One time only, date: 2023-11-01 18:30, lenght: 1 hour.
5. Group of devices: All (including Zabbix Servers)

Result:
When the period is over, the maintenance mode still active in devices (but timed out in maintenance configuration).

After delete the maintenance mode, the maintenance mode still active in devices, and if I click on orange gear says: "Inaccesible maintenance [Maintenance with data collection]"
Expected:

That devices exits from maintenance mode
