[osCommerce] Category depth not as deep as set?

[shotputty]

I have category depth set at 2. (since the beginning). When I create categories it works fine (instantly). But when I create a category within a category it doesn't work. Is this supposed to work at level 2 or should it be at level 3 ?

I need to mention, my .htaccess does not regenerate at all. I used .htaccess information from my other MSU license to get it working.

What are the visible things that change in .htaccess when increasing category depth? I don't mind making some manual adjustments.

If increase category depth, re-generated .htaccess file size should be bigger.
