Hello!
New to Moz and loving it! 
My page https://www.venturesurplus.com/ has a nice optimization score, but the optimization score says it doesn't have a canonical link tag. However, I found this in the source:
Yesterday, there were two, so I cut one out of my themeX.liquid file (I use shopify). I don't do much coding, so I am not sure if I screwed something up by doing that.
Should I disregard the MOZ flag? It is a blue exclamation mark in a circle, not a red flag.
