Layout Picklists

Layout Picklists

Greetings.
I have three different layouts, cloned and modified off of the Standard Layout. I changed the Lead Status - Picklist value in the default Standard layout, however, that update has not completed across the other 3 layouts.

If I go to a cloned layout and try to edit the Lead Status Picklist with the same choices, I get an error that there are duplicate choices. Will the updated Picklist be seen in the other 3 layouts?

Please advise.
Thank You.
