Welcome to the Q&A Forum

I deleted all of the imported posts and reimported them with all tags and categories removed prior to import.  hopefully this will clear it up.  Out of crawls for the day to see if it worked.

What theme are you using?  Different themes implement dropdowns differently.

I generally use heading of the landing page as the title tag. This makes the title tag relevant to the landing page and it also improves the CTR (provided your landing page handing is really Click worthy in the first place).  I use business name at the very end of the title tag and never at the very beginning no matter how big a brand is. I also don't repeat keywords because they don't help SEO wise and make the title tag looks spammy. i hope it helps.
