In order to provide a correct mapping of the image information to the feature class attribute fields, there has to be established a references between the image information and the fields of the feature class. The reference will be configured in Geotagging attributes. Insert a geotagging attribute for every field that is used for mapping the image information and define via context menu which editing field of the feature class belongs to it.

Geotagging attributes configured inside the tool Upload Geotagged Images
Note: Be aware that every editing field has the correct geotagging attribute configured. Every editing field and every geotagging attribute can only be configured once, meaning that assigning a geotagging attribute to multiple editing fields (and the other way round) is not permitted.
