TPMS does not detect RDKS

On my Disco Sport I had 4x Continental S180052076 RDKS sensors mounted on my 18″ original rims. I activated and tested them with a TPMS tool, the no. is displayed etc. (these are original JLR parts. GX63-1A159-AA / GX631A159AA). However, they are not recognized even after 500km. What can this be? Do I still have to program them (by OBD) somehow? Other sensors were detected immediately without any intervention after a few km.
