Speech/TT evaluator - one person automatically assigned to all speech eval's

Hi, firstly, I want to say a huge thank you for the new member area; it's already making a huge difference!

I'm not sure if I'm doing something wrong - I created roles, an agenda template, and a meeting. When I assign a member to be a speech evaluator, the agenda automatically populates their name for all speeches. The same pattern appears in the TT odds and evens evaluator role. All settings are correct; I ticked and unticked everything, but no luck yet. 

Can anyone assist, please?

Thanks, Katarina
