Layout Issue Help Center

Fixed -- Apparently it doesn't like some certain html tags (I stripped everything and redid all my help docs) and now it works as it should.

There seems to be a problem with the layout for Help Center.  When it starts the 4th row of help articles the cards are stretching the beyond what the previous entries are.  I'm not sure what the issue is, but I did see that some articles had NULL values in the DB for what category they belonged in.
