Quote Price not Changing

We have ran into another oddity. One of the salesman went into a quote to make a change. Lets say Line 1 was part number 12. All the correct information from the part master come into the quote fine including the description, price and weight form the part master.

When he changed the part on that line to Part number 15, the decsription and weigth come thru to the quote fine but the price is not changing in the quote.

I tried this on several different quotes with the same result. For pricing we use the information from the Part master.

Anyone else notice run into this and if so can you share the what and why?

Thank You
