RF433 usermod wont accept new rf433 commands

I sucessfull build usermod_v2_RF433. The rf433 codes from my remote are also displayed correct in the info page.
But if i setup remote433.json, it only accept one command from my rf433.
After that it do not detect any new commands.
without remote433.json all works correct.
I use the json api to call diffrent presets.
