New Android Release 2.14.2

Hello.
I am using the Step H widget, and until a couple of days ago this widget accepted negative values.
Now it seems this does not work anymore.
I am using this to set how many degrees to lower temperature at night.
Positive values works fine, but it will not accept -1
or any negative number.
Is it a bug or is it not supported anymore?

Android Blynk version: 2.14.3
