Question about the installation date not exporting out in IFC format

Hi OpenBuilding Froum,
Good day.
I met an issue with attribute not exporting out with the IFC file.
I would like to ask why the parameter called "installation Date" is not exporting out when exporting IFC 2x3?
As the picture below, my .dgn model has added the instance data into the model, however, the IFC format doesn't show the data that I need.
So, Could anyone know how does the setting let the parameter can export the data I want?
OpenBuilding Version is update7.
Thanks and Regards,
Lynn
