intellij- how to remove "bracket" from the project name?

Question

So I have a project in Intellij and I have a tree structure on the left hand side which list out the project name,folders,files etc.

And at the top of the main project, I have my project name in the format of:

 Project Name [XXX] C:\Users\xxx\xxx\xxx\ProjectName

The problem is [XXX] where I can't find any resources as to what it is and I want to rename it or remove it completely. Any idea what do I need to change?

What is that bracket name represents?

Things I have tried:

Renaming the .iml file

Renaming project name in Project Structure

Answer 1

This is due to rename of module not done properly, you or Intellij IDEA would have changed only directory name.

The easiest way to fix this issue is press shift key+f6 / Right click on module Refactor >> Rename and select Rename module, give name same as Project/directory.

Immediately you will see bracket with older module name disappear.

Below is snippet and option to choose highlighted:
