Summary

User Picker fields changes are not reflected correctly in Issue History when the value is removed from the field. This affects both Single User Picker field and Multi User Picker field.

Steps to Reproduce

1. Add a value to a User Picker field.
2. Remove the value
3. Check Issue History and the value still retains in the New Value column where it should be empty.
   • 

Expected Results

• The New Value column should be empty after we remove the value for the field.

Actual Results

• The New Value retains.

Notes

The value is removed properly in the database. It's just that it's not reflected correctly in the Issue History.
This is also only affecting the old issue view. As a workaround, use new issue view and the Issue History will reflect the changes correctly.
