Catalina: crashes when using Replace Text

Using latest releases of Hazel and Catalina. Writing a new rule that will modify file name including replacing some text. As soon as I hit "Replace Text" option in the sub-menu Hazel crashes.
Example screen shots below:
Initial state

Detail of the rule (the Client and Name tokens are both anything). At this stage I have not used replace text.

After running without replace text works fine

Go back to edit script to include Replace Text

The crash
