I think your problem is that you're assigning the same -value to each Radiobutton.

In the following code, Radiobuttons "first" and "second" have the same -value. The "third" has a different -value. When you run it, clicking either the "first" or "second" selects both of them; clicking the "third" selects just that one. 

use strict;
use warnings;
use Tk;
use Tk::Radiobutton;
my $rb_value;
my $mw = Tk::MainWindow->new;
$mw->Radiobutton(-text=>'first',-value=>'one',-variable=>\$rb_value)->
+pack;
$mw->Radiobutton(-text=>'second',-value=>'one',-variable=>\$rb_value)-
+>pack;
$mw->Radiobutton(-text=>'third',-value=>'three',-variable=>\$rb_value)
+->pack;
MainLoop;
print $rb_value,$/;

Changing the -value of the second Radiobutton to 'two' makes it independent from the first.
