Steps to Reproduce

Automation Rule:

1. Create a new Automation on a Service Desk project;
2. Select the Issue Created trigger;
3. Add an Edit Issue action, and select the Assignee field;
4. Select a user, click add and save the automation;
5. Open the automation again and click the pencil icon to edit the action;

Request Type:

1. Add the assignee field to a request type and hide it;
2. Select a user, click on "Set";
3. Edit the value again;

Expected Results

The selected user is displayed as the chosen assignee.

Actual Results

The assignee is displayed as "Automatic".

Notes

The user is actually stored properly, it's just not being displayed properly. If you try selecting the same user again, the option to save the automation will be grayed out as no actual changes were made.

Workaround

Currently, there is no known workaround for this behavior, but please note that the actual value is being stored. A workaround will be added here when available.
