Eb3 Downgrade issue

[new2h1]

Hello, 
My Eb2 to Eb3 downgrade has an issue. I-140 and 485 were filled in concurrent. 
My I-485 was accepted but the receipt notice says "Preference classification" as "Employment based 2nd"  instead of saying Eb3.

Now what needs to be done so that it is corrected to Eb3? 

This is very frustrating that they mess up like that.

Check with your attorney, if you have used an attorney to file 485.
