You should ensure that you have the correct version of EnergyPlus set before exporting IDF data for use outside DesignBuilder.
DesignBuilder will automatically generate compatible IDF files with the target version of EnergyPlus as set on the EnergyPlus tab Program options dialog. If you are generating IDF files for simulation outside DesignBuilder you should note that, by default, DesignBuilder targets an internal version of EnergyPlus which has an extended IDD data definition file to allow:
