Thank you for your question.
You have indeed taken the correct steps to making the change by selecting 'ByText' and providing the correct 'SelectionText' by changing the value from the dropdown, or alternatively from the properties.
The custom description text of this step may not have changed because it has been 'customized'. If you were to Right-Click said step -> 'Remove Custom Description' before making the changes then this description will update appropriately. You also have the ability to fully customize it to anything by selecting 'Edit Custom Description'.
I will be happy to answer any further questions.
All the best,
the Telerik team
