Hello @Kevan-Y,
Thanks for the update. I see one issue when you don't try to change the name.

Steps to produce the bug:

1. Create a new folder say demo1
2. Clock on edit folder name.
3. Now without editing the name, click on green tick.
4. You get an error for saving the save name.

Generally when you don't change anything in the name, it should accept the existing name.

Steps to produce another similar bug:

1. Create a folder with the same name as an existing one.
