Turn off make up function names that does not exist?

Is there a way to get auto complete to just auto complete and use existing methods? I just want to turn off the method where it makes things up. 

For example, if i have a function called fetch_expected_isrc_asset_lookup_count and type myclass. it suggest things as get_expected_isrc_asset_lookup_count which is a method that does not exist anywhere in my code, it just made up a method name. I find this incredible frustrating about pycharm. How do i get it to stop suggesting new methods and making up parameters that they take and suggest things that actually exist?
