we just upgraded from 2018 to 2020.  

apparently there are some differences in BOM tables between the two.  when I first added a BOM to a drawing that contained multiple configurations the header in the BOM table was not updating for each configuration.  after searing a little, I found that I needed to click a box in the BOM table tab for document properties.

this got me my individual configurations, but now I have a "/" symbol after the configuration number.  so my column header displayx 10032600/ and I only want it to display the number

if I double click in the header cell to edit the header, I can only edit the text I've added.  which is the "QTY." text on the second line.  I don't have access to the config line of text.

anybody know what to change to fix this?

Thanks
