How to fix the classifieds tab position in bp-nav? Classifieds tab stays in default position.

Although the classifieds plugin that I have works fine, I can't change the order of the classifieds menu tab for the front-end screen "bp-nav". I used the following code -

$bp->bp_nav['classified']['position'] = 5;
- in my bp-custom.php file. All the other menu tabs are in the correct order, but the classifieds tab stays in the default position. I should mentioned that I also tried updating this plugin, but the update available message on my dashboard does not disappear. I don't know if this may have something to do. Is there another way I should try to custom position the tabs?
