Are you sure of your equation (the 1/a part) ?

If your equation is OK, the numerical solver returns results with a guess <> 0 (because of 1/a ?) : a=1.3447... a=2.2067... etc.

EDIT : same problem with guess = 0 on the Prime... and same results...

What function are you calling to find the roots on the Prime? If you're calling solve, fsolve or nSolve from HOME you might get "unpleasantly surprised". Have a look at this thread.
The Solve app will work as expected though.

I used the APPS Solve. (Don't work with guess 0 => On )
