Missing image when exporting

When I try to save my slideshow to mp4 one image is missing in spite of showing when playing the show in FM4. I tried to save this image slightly different out of Lightroom: same error. I tried to delete this image from the show rename it and import it again: same error.

Other suggestions?

Tried to export the show with FM 4.4.8 and with FM 4.6.2: same error.
