P: Non-destructive blur for masking doesn't save correctly anymore

In the recent day's it work for me, so I think only the last update could cause it.
If I use in a common mask the "blur"-function in the property panel PS show's it correct. But if I save it and look in LR for it the blur-effekt isnt present. Also if I save it as jpg from PS or LR the blur is vanished.
