zoho crm field

zoho crm field

using the zoho crm field button on our forms and recently the data it pulls over is from the same form but not the field we want.
Example

product name .  screwdriver
product code .    scr11
price . 9.99

if there is no product code it will use product name but if there is it pulls over the code instead. It did not use to do this and the girls in the office are shouting loudly at me.
