Error 2019b simulink plotting

Hello.

There were no problems in the previous version, but the problem in the 2019b version is as illustrated.

Also, if it places the constant at the input value, that will place it in a circle as shown in the figure below.

Does anyone know the cause or solution of this problem? Please.
