If I remove a column but do not save this change, I should be able to see the column name on add column screen

[FFrancieli]

When I click on remove a column and then cancel the removal the column remains on the screen, but is not possible to change the column name.

Steps to reproduce error

1. Click on "Column" button.
2. Click on remove for any column
3. Click on "Close" instead of save
4. Click on "Column" button again.
5. I can only remove the column if I click on "Save" button, but is not possible to change the column name anymore.
