Wiki Translation ( Some .po Lines dont work )

Hi there,

Im translating wiki plugin to pt_BR, and i came from found a little problem:

Revision for “%1$s” created on %2$s
that i have translated to:
Revisão de “%1$s” criado em %2$s

and

Compare Revisions of “%1$s”
that i have translated to:
Comparar Revisões de “%1$s”

dont have worked.
Were can i change on plugin code? Or,
Can you verify & make an update of that?

All my others lines are OK, except that two lines.

Thanks for youre feedback
