When using UI11 and the Firefox browser, the CI Relations formatter is causing a Field label issue.

1. Open an instance using Firefox 47.
2. Switch from UI16 to UI15:
   1. Click the gear icon  in the upper right corner.
   2. Click Switch to UI15. 
3. Switch from UI15 to UI11:
   1. Enter sys_properties.list in the navigation filter.
   2. Press Enter.
   3. Locate and open the property named glide.ui.doctype.
   4. In Value, type false.
   5. Click Update.
4. Navigate to Configuration > Base Items > Computers.
   Note that the Field labels are not displayed correctly.
   
   

Possible workarounds are:

• do not use Firefox
• remove CI Relations formatter 
• use UI15 or UI16
