The CPNY F-PLAN REQUEST field being grey usually means the FMC does not currently see a company route to request. In the EFB, confirm the SimBrief OFP has actually been imported/generated, not just entered, then use the EFB option to send/import the route to the FMC. Also check you are using the same SimBrief pilot ID and that the route has finished processing. If it remains grey after that, report it as a possible bug with your exact steps.

This sounds like the EFB map’s terrain layer may be using a separate cached or online map source from the sim’s TERR data. Since ND terrain is fine, I’d try clearing the EFB map cache, and the sim rolling cache if the EFB uses it, then reload the flight. Also test different zoom levels and note whether it only happens after panning or correlates with online/streaming settings, so iniBuilds can reproduce it.
