Title: Manual Configuration Information Not Saved in Toolkits in a specific scenario

Description: The configured information for the Manual configuration type in toolkits (Jira, Confluence, or GitHub) is not saved under specific conditions. After switching from Manual to Personal or Project configuration and back to Manual, the configuration information is lost.

Steps to Reproduce:

1. Create an agent.
2. Add one of the following toolkits: Jira, Confluence, or GitHub.
3. Save the toolkit.
4. Create a Personal or Project configuration.
5. Change the toolkit's configuration from Manual to either Personal or Project.
6. Save the configuration.
7. Save the agent.
8. Change the toolkit's configuration back to Manual.
9. Reconfigure it.
10. Save the configuration.
11. Open and verify the Manual configuration.

Actual Result: The Manual configuration's information is not saved and appears empty.

Expected Result: The Manual configuration's information should be properly saved and available.

Notes:

• This issue affects the reliability of configuration management within toolkits.
• Ensure that switching between configuration types retains all entered information.
