Katalon's keyword package folder automatically changing its first letter to upper case in File Explorer


In my Katalon project, under Keywords folder, I have created a package called com.test

My problem is that in File Explorer, the package folder ‘test’ keeps automatically changing to ‘Test’, which means that all my keyword classes in package com.test are failing.

Here are some errors I am getting:

Class file collision: A resource exists with a different case:

Groovy:unable to resolve class com.test.MyKeywordClass

The declared package “com.test” does not match the expected package “com.Test”

What could be the reason that the folder keeps automatically capitalizing its first letter? I have changed it back to lower case multiple times, but every now and then it keeps capitalizing the first letter again and causing errors in my project.
