LVS, PEX, PEX_RUN environment variable issue

I am trying to run a simulation on an extracted view of my APR design. The design passes LVS when I set PEX_RUN = FALSE. However, when I set PEX_RUN = TRUE, LVS fails (PEX does complete and create a calibre view). Because of this I am not able probe any internal nets in my design while simulating.

 

What I noticed is when PEX_RUN = FALSE, the fets in my layout are netlisted as "nfeti" (the same as in the schematic). When PEX_RUN = TRUE, the fets in my layout are netlisted as "nfeti4" (not the same as in the schematic).

 

Does anyone have an idea of how I can fix this issue? Thanks.
