Stupid error message piss me off

I keep receiving this kind of error message from PV360
It asks me to save the file with tessellation data, in fact thisoption is always checked by default. So what can I do with it?
I open the assembly file many times and save, rebuild, still getthe same error message, it really frustrated me.
