cut list angle rounding

Hello,

I have got this problem and I can't understand why.

When I round the cut list angles of a model same angle cut's aren't rounding to the same value and I don't know why.

attached are the two files where you can see the angles 8º and 7º are rounded from 7,50º and both of them should have been rounded to 8º.

What is going on?

Thanks

M. Costa
