LBWE End phase Message No. D0322

I want add custom fields to 2LIS_11_VAHDR. I have appended ZZ fields to MVBAKUSR which is an include for MCVBAK. I am then using LBWE to add these to the extract structure. I add the fields from right to left in LBWE. I green tick and add to transport. I then get an information pop up with the warning:

End phase 010 ***********************************************************

Message No. D0322

Ive tried taking it out and redoing it a number of times but always get an error (although previously I think the error was End phase 005.

Any idea what this means? Everything seems ok but it seems strange I'm getting this.
