Wrong default customer price list in Quotation and Sales Order modules

After upgrading to latest cloud version a bug came along, when doing a quotation or Sales order, by the time I select a customer the wrong default customer price list is fetched, if I delete price list permissions to all users the process get fixed but that will allow any of my employees to see buying price lists which should be exclusive information for the system manager or purchasing department employees, any help to solve this issue please?
