Currently, I'm migrating a website from Magento 1 to Magento 2. I've used the data migration tool and moved my data to Magento 2.
When I try to update a custom attribute called '
color_sw_selection', an error occurs like this "The value of Admin must be unique."
Even if I select the "Unique Value" property as "No".
I'm using Magento 2.3.2
