It is possible that when taking a photo, this image is saved with the name of a specific column, at this time it renames it with the key column, which does not serve as the text of the image.
The naming conventions are in place to avoid duplicate names. Currently we don’ythave the ability to modify them.
If the text you are referring to is that which is shown in a Gallery view, I would suggest having an additional column allowing the user to type any text they wish to describe the image. This can then be shown as the image label.
