Item Tracking + get receipt where multiple receipts problem

Navision Attain 3.10.A

An item tracking purchase line for a quantity of 13 has been received in 2 parts, qty 1 receipt A and qty 12 receipt B

When I try and invoice the lines using the "Get receipt Lines" function, all seems OK in the Invoice but I get an error on posting;
"The Purch. Inv. Tracking Line already exists", "Document No. xxxxx, Item Tracking No. xxxx, Line No. xxxxx"

Looking at the Line/Item tracking lines from either line shows 13 tracking lines.

My question is this; is this normal for this version?
Is it possible to use "get receipt lines" for multiple receipts where tracking is used?

If not, how do you get over the problem?
