Flex Fields are Local
Flex fields are local fields, meaning they are only available in the current structure. You can delete the column and reuse the flex field later – it gets saved under the corresponding field menu – but it isn't available in any other structure.
This allows you to create as many custom fields as you need for a specific structure, without cluttering up the column menu for everyone else!
