The X100P has not been made for years.

No, what you are experiencing is not normal.  The two ports on the card 
are electrically wired togather, much like a standard phone splitter you 
would buy at a store.

The only cause I can think of for what is happening is either a bad 
X100P, a card that claims to be an X100P, but is not, or (maybe) your 
red/green are swapped.
