Rating appearing on aliased beer

I noticed something odd on my ratings yesterday. I seem to have a bogus rating showing up.

If you go look at my ratings you will note that rating number 5 is:

Rhinelander Boatswain Double IPA Rhinelander Brewing Company LLC Imperial IPA 4.7 9/15/2017

Rating number 4 is:

Minhas Imperial Jack Double IPA Minhas Craft Brewery Imperial IPA 3 2.47 9/15/2017

Rhinelander Boatswain Double IPA is an alias. I rated the Minhas. Yet Rhinelander Boatswain shows up with a score of 4. 7.

So do we have a bug here?

Something is definitely wrong if a Rhinelander is getting a 4.7 ;)
