Have you created depedency (selection condition ) for this 2 components at BOM position , it seems there are no selection condition attached and thast why all the components from BOM are getting selected.
Please create condition like below syntex and attached it to components.
for component 1 , selection condition
$SELF.CR_68_MONITOR_M_S = '88000922'
for component 2 , selection condition
$SELF.CR_68_MONITOR_M_S = '88000320'
check & reply.
Thanks
