With no example of the formula you are using, it is much harder to see what
is going wrong. I would suggest changing iteration to 1, and then pressing
F9 to step through, and see if there is perhaps a repeat of one of the
values, or a 3rd unknown value that is appearing.

I have a circular reference in my worksheet where I get two sets of values
for the same input as the circular flips between two values. I have set
the
iteration to 100 but the values in the sheet do not give the same answer
each
time.
