window - procedure parameters

Is this a bug or am I doing something wrong

I have copied a window that was set up as a procedure with 2 parameters
in the global declaration off the window I have changed the name of the 2 parameters
when I generate the header comment the old parameter names are there
when I want to add a 3 parameter this is not recognised in the complete program it gives an error because off the wrong number of parameters passed

when I look in the under variables I see the old parameters and the new ones but I can`t find where those old paramters are stored, how can I delete these

the only place I can find this is in the generated header comment and nowhere else

even search doesn`t bring anything else

when I "hoover" over the variables the "old" variable names don`t give any extra info
the new names give the comment info but in the comment info is the old name shown

when I go to test this window also the old variable names are shown and not the new ones
the window functions normally

what am I doing wrong
