American Wheat beer (from john palmer) need info please

I want to do this recepie from his book. P 215. Not the online version it's seems to be different.

it's pretty clear how to brew it except for the hops section

it reads
0.5 OZ Sterling (7%) @ 60 min 13 IBU
0.75 Oz Liberty (4%) @ 30 min 9 IBU
1 Oz Liberty (4%) @ Blank 105 IBU

So what does the blank mean? Does it mean knockoff ? I looked at the other receipes from the book and when he means knockoff there is a 0 and it's not blank. Is it a mistake or a typo?

What should I do ?
Any help here would be great, I have all my ingredients and ready to go.

Thanks
Ernie

10 minutes, 5 IBUs maybe?

The online versions assume partial boils. The book versions use late extract addition to offset this, so they have lower hop quantities.

Looks to me like it should be 10 minutes and that will add 5 IBUs. Because you will be hard pressed to get 105 IBUs from 1 0z of Liberty!

makes a lot of sense.. 105 .. 10 min- 5 IBU's .. why didn't I think of that! because I'm a rookie. Thanks a lot.
