Wire disappears when trying to connect connection point of a symbol... Why?

I am new to Solidworks Electrical. But I think I getting a hang of it although few things like this stump me.

I am trying to connect a terminal to a symbol with a wire. Sometimes the section of the wire that connects to the connection point in symbol disappears. 

I am unable to attach the video for some reason. But here is the link.
