Welcome to the Q&A Forum

Hi there. Do any of those navigation links have nofollow attributes or 302 or 4xx statuses? Also it might be due to crawling history on your website. OSE relies on data from MOZscape crawls, which means that if your website is fairly new or haven't been indexed often enough for whatever reasons, it will be showing fewer pages. links etc overall. Also, since MOZbot has the crawl limit per domain, and you have thousands of pages, the issue might be that mozbot reaching limit before crawling every page. Hope this helps.

To start i am not a BIG fan of directories as they sometime takes long and give little benefit to the overall project. I would recommend you investing your time on some other valuable stuff then this! But as you asked for it i can provide you one resource that have the list of legal web directories... http://www.web-directories.ws/Niche/Legal/
