IF your here for help, then i suggest you do what was asked earlier and list what flavors you put in this juice(that includes the manufacturer of the flavors)? separation like this isn't normal.
its extreme soda flavoring from mt baker
You should be fine, just give it a very good shake this time.
It is not normal, but not unheard of, especially if the mix is VG heavy. There are a few flavors that do this.
Personally, I would get new batch of flavoring and see if it does the same thing.
TFA's Red Hot flavor does this, too.

> * Note: cinnamaldehyde can vary from being slightly yellow to very yellow, and so there will be color variations with this flavor. Also, this flavor does not combine well with VG-only blends.
Emphasis mine.
Okay, so evidently I'm weird in having this happen to loads of my mixes. Almost everything I make separates a bit until it has been well steeped and shaken a lot. I also mix in the bottle so there isn't much shaking room. None of my flavors are oil based, they are all pg based and used frequently in everyone else's mixes.
