GP7 EL Pack Engines do not render in TS2021

Have a problem with the GP7 EL Pack: in Build mode the engines can be added to a scenario and appear "normal"; however, when scenario is saved, the only visible components are the couplers, no hood, etc. Straight out of the RWP (dated 12/12/2019) install, no modifications to either the bin or GeoPcDx files for any of the paint schemes. Thanks for any assistance.
