I added a task to PP checklist for Listing:  "MLS: Review description closely for errors/typos before going live"
This seems to be a consistent problem and so trying to nip it in the bud.  I know some of the descriptions are cut and paste and some are re-typing from embedded documents so not sure where the errors are coming from but it looks bad to clients.  Hoping this will alleviate or at least minimize the problem.  The devil is in the details as they say..  Thanks!
