Moving Prospects

I inadvertently added two prospects (Ginelle and Zina) to our Membership roster on Southeast Houston Toastmasters FTH (5324194). I can't move them to "Prospects" after I have selected their name (by checking the box on the left of their name, then selecting the tool, "Move to Prospect List").  I get an error that says "You must select one or more activated people in the list below first, before selecting this tool."I did select the member first, then the tool....I got the error message.

Any suggestions on what I can do to move them to the Prospects list?

Thanks!

Delete and readd in correct list.
SInce they haven't approved it won't make any difference to them.
