No binding data in bound table in WPF

[Bear89]

Not sure if anyone can help me with this one. I have 1 parent and 3 child tables in my WPF design, with the 3 child tables bound to the parent using drag and drop from the datasource. However, one of the tables displays no binding data. When I check its Bindingdata resources they are all present, and if I change the resource to another bound table I get all that table's appropriate bound data. I can find the names table in XAML but the table doesnt have all the descriptors that the other children have.

Not sure how to get these data back. I have tried deleting and dragging and drop, but the same behaviour recurs.

Any thoughts?

I've managed to find 2 errors in the debug, and these relate to the troublesome table and to binding:

System.Windows.Data Error: 40 : BindingExpression path error: 'Table1Acctdetails_Unpaid' property not found on 'object' ''DataRowView' (HashCode=3571397)'. BindingExpression:Path=Table1Acctdetails_Unpaid; DataItem='BindingListCollectionView' (HashCode=56999299); target element is 'CollectionViewSource' (HashCode=16127101); target property is 'Source' (type 'Object')
System.Windows.Data Error: 40 : BindingExpression path error: 'Table1Acctdetails_Unpaid' property not found on 'object' ''DataRowView' (HashCode=15961928)'. BindingExpression:Path=Table1Acctdetails_Unpaid; DataItem='BindingListCollectionView' (HashCode=56999299); target element is 'CollectionViewSource' (HashCode=16127101); target property is 'Source' (type 'Object')

But I can't see where this refers to in my code, either in my own code or the automated code?

And just for completeness, here is my entire debug output - hte only other errors are the dll exceptions, which dont seem to be the key issue?:
