PCB Editor | Netlist/refdes List Not Updating

Hello,

I am currently using Allegro Design Entry CIS 16.2 and am attempting to have it take my netlist and port it into PCB editor. Problem is, when I go to place parts, I notice that whenever I update my schematic, those updates are not being implemented into the PCB Editor. The only refdes names and schematic line connections remain while the new changes are nowhere to be seen.

Any ideas? I am also presented with a message when PCB Editor opens that states "WARNING(SPMHOD-33):Database was last saved by a higher tier tool…… Allegro Expert."

Any help is appreciated. Thanks!
