PLEASE HELP

I am a registered SWX 2021 user and have lost my way with how to correct my SWX bom
My previous bom would correctly transfer weight from each part and multiply it by qty. 
Ever since 2021 was installed, I get a part which shows the weight of 45kg, but in the BOM it show the weight as grams: 45668.91
I cannot figure out how to correct this, without editing each part line in my bom. 
Can anyone please give me a proper working copy of a BOM for parts?
I can install it, But I do not understand how to correct this
I know the weight is accurate on my part, but I cannot correct this in my BOM
please forward me a working copy to moic99976@gmail.com with BOM SWX 2021 in subject line
Thank you
JB
