The Import IDF functionality in OpenStudio is meant to provide an entry path to OpenStudio for IDF files, but isn't intended to round trip back to that IDF file. The import focuses on geometry, constructions, loads, and schedules.
You may want to look at the Inject OSM Geometry into External IDF measure on BCL, that is setup for specific use case where someone wants to use IDF based workflow but leverage some OpenStudio geometry measures. The idea to inject the updated geometry back into the original IDF file, vs. relying on OpenStudio round trip translation of the entire IDF. Workflow would look something like this. - Import IDF file into OSM - Run OpenStudio measure to modify geometry - Run EnergyPlus measure mentioned above to inject modified OSM geometry into original IDF.
This measure adjust the zone names back to what was in the original IDF. For reference there is an enhancement request related to this behavior in the reverse translation used for import IDF.
