Well, your posted links are "forbidden" so we cannot look at anything. In the past this has been caused by mal-formed geodata. What you list above is either an indication of the problem or a summary of the data.
There should be separate entries for the latititude, longitude, latitude reference, and longitude reference. The latter two are the N/S and E/W references and are defined to be simply a single character. Zenphoto follows this standards definition. If, for instnace, the N and W are part of the latitude and longitude strings it will fail. As would be the case of the references are not the single character N, S, E, or W.
