I just found out a post that contains an answer and the answerer comments
Either you provide us with a screenshot/photo of the "MINUS SIGN" you're talking about, or I'm done helping you.

We have just entered public beta so shouldn't we be a little more of Helping nature to newer users?
Note: I have flagged the comment.
