Farms big 100 - who sees ads compatibity

Hello, i have this pack and was of the understanding that it was compatible with plugin, who sees ads, which requires following entry in index.php

<?php if (function_exists('wp_ozh_wsa')) { wp_ozh_wsa("336280nocolor"); } ?>

Thing is i have just noticed that with the theme, "Almost-Spring" it does not have that instead it has:

<?php if (function_exists('wp_ozh_wsa')) { wp_ozh_wsa("336x280-almostspring-top"); } ?>

Point is that how many of the other 100 do not have correct WSA code in them or am missing something?

cheers
