Welcome to the forum!
Was there more info given in the chat? I'm not clear how the objects lost their unique IDs.
Using 0.92.3, it seems to be working properly.
This is not a feature that I have used very much. So I did learn that I had to be sure and click the Set button, in Object Properties dialog. Otherwise the names are replace with the random id. I'm not sure if the Set button is new, or if it has always been there. But after using Set, and exporting, all the objects kept their same name.
I have not yet upgraded to 0.92.4. If I have time later, I'll do that, and test again.
