Flavourings expiration date

I went to a vape shop near me and got a cherry flavouring the brand is supposed to be from my country and it's called atmoslab not that anyone would know just saying and anyway they show the manufacturing date and they say it expires 24months after that sooooo that means it expired in May of 2020 lol

I will get it back to them for sure to replace it but I wanted to ask if anyone knows if those flavourings really expire?
I mean probably they may last more than that? Anyone ever had…
