No dropdown menu for 'Actions'

Hi there, 

I am new to Innovator. I want to add member to Change Specialist I, but the dropdown menu for 'actions' is empty. The account I use is root. I noticed the dropdown menu in 'New Part' is empty too.

Aras Innovator Version 10.0 SP2  Build: 5907

FireFox ESR 31.7.0

Would you please help me on this issue? Thanks.

Best,

Gang
