What you see in MWO is the Object ID, the web client however shows Object ID and Description (just click the highlighted link in your 2nd screenshot to verify). So it’s not a bug, it’s just different fields.

Hi ​@Alexander Heinze 

Thank you for your reply, but is it not the same reference field which sould display Object ID and Description combination in both environments (MWO and web client)?

In my screenshot you can see after the Object ID it has this separator (‘-’) visible like web client but description is not available.

I think discription value is not fetching here.
