Missing PI Grips in SS10 profile geometry

I have a profile that was created quite some time ago in Inroads SS2 and brought into Power Geopak SS10. The profile is several miles long.

I want to make some minor changes but am noticing the "grips" with station, elevation, and grade control for PIs are missing. Only PIs though, I can move and manipulate PTs PCs and curve lengths:

I've noticed this before on other profiles I've imported that were created in SS2, but they were always shorter ramp profiles. If I needed to just drop and recreate it wasnt a big deal. This profile being several miles long, I dont really want to do that. Does anyone know a workaround or way to make the PI information fill in?

Thanks
