Heated build plate not holding temp

I just upgraded my Replicator 2 to have a heated build plate. When I run any model after preheating the HBP just starts dropping and will not keep any heat.

I upgraded to sailfish and still have the same problem.

Should I change my makerware profile to Replicator 2x so I can set the plate to on or is there something else that needs done.
thank you

fixed with a edited .json file
