I have a BOM with weldment and sheet metal parts that I'm trying to dissolve so that each length of tube and size of sheet is shown as one line item with a total quanitity needed for the job. When I dissolve the weldments with tubes, the correct quantities and lengths are shown. However, when I dissolve the sheet metal parts they all combine into one line item with a total quantity for all sheet metal parts regardless of thickness or size.

Tubes are correct:

Sheet metal is not correct

Any idea as to why this is happening? Is it something on my end that I'm not seeing?
