How to rearrange functions in PyCharm.

According to the docs I should be able to rearrange my functions.

https://www.jetbrains.com/help/pycharm/reformat-and-rearrange-code.html#tabs_and_indents

Note it says in the dialog that opens that there will be four options, but I only have 3

Note there is no option to rearrange code as the docs say.

The docs also say:

Rearrange entries: select this option if you need to rearrange your code based on the arrangement rules specified in the code style settings.

So I figured maybe I need to set arrangement, so I followed arrangement rules link,   It says to set the arrangement in the arrangement tab under code-styles but I do not have this tab either.

It's somewhat frustrating when the docs don't seem accurate, so anyway how do automate rearranging my code to alphabetical order for the functions.
