Creative Cloud showing picture dimensions incorrect

Adobe Creative Cloud shows some pictures in false dimensions. Usually spreads them. This is not nice as we are using CC to present photo proofs for customers. By this far we have not found anything that would be technically different with these pictures. We have also tried this with several accounts and several image collections. Always the same thing. Some pictures with false proportions. I think this is just something that goes wrong in the Create Cloud system. Any way to avoid this?
