I am not sure, but I only used a hopped extract one time only.
I would say go ahead and use whatever recipe you got this time, and use unhopped extract until you get a chance to taste this one after it has been in the bottle a while.
Thanks all; I should have mentioned that I was adding Munton's Hopped LME to Brewsmith software and wanted to be sure that I had the characteristics right.
I used hopped LME in an Irish Ale that came with a kit, I added a bunch of other ingredients and wanted to see what the overall IBU was.
