While executing APQA-373 it was discovered that changing selection in drop down menu for 'Select Worker' under 'Services' does not lead to UI changes.
Step to reproduce:
• navigate to 'Services'
• enter a name and click 'Add'
• select the service and click 'Edit Service'
• select different options in drop down menu for 'Select Worker'
The work around is to save the selection and then enter the editing again - then the changes are there.
