Those files are not a Catalina installer. Where are you trying to download the installer? See How to upgrade to macOS Catalina.
I don't know what more to tell you. I am having trouble understanding your English but these files you have posted are not Catalina files. I do not know what problem you have with Catalina. The Catalina installer is named, Install macOS Catalina.
The filenames you have posted are from 2016.
