I am a student studying basic organic chemistry (isomerism) and was asked a question to find the number of aromatic isomers of $\ce{C7H8O}$.In fact this was a question in IITJEE exam. So I tried to draw all and I found all but the problem is that I found more than all. The answer to the question is 5 which may be wrong(I don't know) but several websites state this. Here are some links to those:

Here is the list of isomers I found:
So what is wrong with the list of my isomers?
