FOTT bug report - Invoice model incorrectly reads invoice

[DSCmattb]

Describe the bug
A clear and concise description of what the bug is.

The image above shows the table, but the data is selected as a single line item. I would have expected at least the top line and serials to be merged (maybe not because they are clear new rows), however the freight line is completely skipped all together and is rolled in to 1 line with the amount of the first line.
