Can't move method

I am using Webstorm 2018.2.2

According to Webstorm IDE,if I select Refactor -> Move in the dropdown menu. it tells me at the bottom of the IDE...

Move the selected method, class, static package to another package or class and correct all references...

Yet if I select a method in my TypeScript class, and Refactor -> Move, the Move Module Members window appears, but it only allows me to select my class name, it wants to move the entire class somewhere, which is not helpful, I only want to move certain methods in my class into another class.  


This is poor method refactor support and I expected something like this to be working in a Jetbrains product. 

Why does this happen? Why do the class method names not appear?

All the methods are static.
