Version Confusion

Is it just me or are there too many versions of 360?  Standard, Premium, Ultra, etc. plus add ons.  When I look at my account I'm not sure which ones I own and which ones are promotional and which ones are old but somehow still active.  Even when I look into my account it shows both Norton 360 and ultra both active.  Should this be?  Also it shows a member since 2023 but I've been using this since the early 90's.  I'm just getting more and more confused.  Please simplify the registration and version process.
