More missed messages with longer cables with nRF24L01+?
the Antenna is interfering with the signals because of its proximity to the point on the bread board where you are connecting the wires, as Majenko said.

If you rotate the nRF24L01 board 180 degrees you will increase the distance between the wires and the antenna and this will reduce the interference, but because of the way radio waves propagate there is also a chance that it may make it worse.  The radio wave propagate from the antenna in a share particular to the antenna.  I don't know what shape this antenna puts out, I'd expect it to be omnidirectional (all ways) because of its purpose.  However all directions are not equal because of reflections, the shape of the antenna, defects in the shape of the antenna, etc and if the pattern of the propagation can be mapped you can identify the make of board and if the mapping is accurate enough even the instance of the board itself.

So, to cure interference:


Increase the distance this reduces the power of the interference by the square of the distance.
Change the orientation, usually by something other than 90 or 180 degrees.
Shield the wires.


In short move the antenna further away from the wires, can you use MF DuPont wires to remove the radio from the breadboard all together.  The fact it won't sit still and is sliding all over you desk will probably help with reflections.
