Has the account been charged again since the missionary returned to service? If the missionary has just recently returned to the field and the account hasn't been charged again then I expect the action item will go away once the charges start again. If charges have been made recently then you'll probably need to call the global service department and report it to them. That action item is new and there have already been some problems with incorrect notices so it could be a bug. Or it could be that CHQ needs to do something to the account to remove the notice.
