Glideslope is being stubborn

hello all!

I have been trying to insert my custom ILS for MMMZ airport (since the default has the glideslope right on the threshold). I can build the package, and i add all the ils properties just fine, but the default one is still overriding mine. I have checked parameters to make sure i am not missing any, i have also made sure to use the delete function for the ils. Anyone have any thoughts?
