ROON help needed

So, I finally tried Roon, (got a deal for a 60 day free trial) without really knowing what the hell I was doing and of course, I am even more confused than before.

I went to listen to Tidal yesterday and found under "My Music"/Albums on Tidal that it now had more than doubled the amount of titles in this file?  Over 90% of what was added, I would never listen to. 

I first thought that someone got into my Tidal account and added all of these.  I went into Tidal and changed my password.  Then I found a way to see what date these titles were added.  It was more or less the same time I added Roon.  Is this what Roon does?  My playlists and artists were still all the same, (nothing was added to these files).

So far, I am not impressed with Roon.  I'm sure it's because I have no idea how to use the damn thing, but for the limited use I have with it, I have found very little use for it.

What am I doing wrong?
