DO you mean its just information or that there is something wrong? In the middle of a build I don't want to be frightened that the database is going to be 'corrupted' . Its not clear from the UX of this if any action is required

This warning appears when the content column type of the current selected field is different than the new one -> you'll lose all the information that is currently stored.

For example: changing from number to text won't be a huge problem but changing from text to date will result in a data loss
