Bad PG? Sweet smelling PG from vape king.

Hi guys and gals, long time first time.
Hoping someone can give me some advice on what i should be expecting from plain, unflavoured PG. I just received a 100ml bottle i bought from E Cigs & Accessories - Best Online Retailer in canada - Vapeking and it has a very distinct sweet smell, kinda like caramel candy. Is this normal for PG, this is my first experience with it but i have read it should be odourless and that a sweet smell is characteristic of ethylene glycol. Is this something i should be worried about?
Thanks in advance guys.

 

I don't have an extensive experience but so far all my PG's were odorless and colorless
