What is your current version, Adel? With the version 1.5.5, you can use the decimal values. See the reference screenshot: https://prnt.sc/pfg7uu
As I suggested to you on your previous topic, if you are running with the latest version 1.5.5 and yet having these problems, please feel free to get in touch with our support. Sometimes the problem may occur based on the user site environment which we need to check first.
Thanks
