I can now see what your problem is. The first sentence that I quoted from you above is incomplete. It should read that "lght has only one speed relative to any inertial reference frame". Inertial reference frames move relative to each other with different speeds. Nonetheless, RELATIVE TO ANY ONE OF THEM you will measure the same light speed c. You are making the mistake of adding the light speed relative to an observer moving relative to you as if this light speed can also be measured relative to your reference frame. This is not possible because both of you can only measure light speed to be equal to c within your respective inertial reference frames. I hope this helps.
