Tunisian national anthem problem

Soo i was playing with tunisia in a friendly match and i let the players sing the national anthem before the match when i was hearing the Tunisian one i was surprised that the anthem was wrong and they displayed an old one from more than 30 years ago that today we no longer use . Ea i want you to change the anthem to the new one please and quickly because it can be misunderstood by tunisians?

The new one is houmat el hima
