Bug

Is not posible to update the Status an event in agenda as "Not aplicable" instead "to do"
This means that every upodated event will be transformed ina a task "to do" even is not a task.

Environment

• Version: 14.0.1
• OS: Linux64
• Web server: Apache/2.4.46 OpenSSL/1.1.1g mod_jk/1.2.41 mod_bwlimited/1.4 mod_fcgid/2.3.9 Phusion_Passenger/5.3.7
• PHP: 7.4.7
• Database: MySQL or MariaDB 5.6.29
• URL(s): https://mycompany.com/comm/action/card.php?action=edit&id=3698

Expected and actual behaviour

Now is possible to create manual events in the agenda to register the content of a Telephone call for example, and register the event with Status as "non applicable", that is very convenient since is not a task to do, is just the registration of an event.
But unfortunately, if you modify the event to update any data, then the status is switched to a type "to do", and then the event is converted as a task to do, even is not a task.

Steps to reproduce the behaviour

• Create a manual event in the agenda with status/percentage type as "not applicable"
• Modify/update the event after creation
• Observe that is not possible to save it with the status/percentage type as "not applicable" any more.
