Problems with JFLAP

I am trying to use JFLAP. I have made the following NFA:

from a book that corresponds to the regular expression: (a+b)*ac. ('+'=OR
and '*' = Many or nothing)

But when I try to convert it to the a regular expression to see it it
matches (a+b)*ac I get:

followed by:

>From this last picture it seems that the expression is a+bac which is not
(a+b)*ac.

Hope someone can help!
