The image information for multilayer openexr files are only shown on the first draw. In the second draw the render result property is filled of the image, making blender think the image is a render result and it want to display information about the renderpasses. Which are not present. It could be that in the first draw the image data is not requested as the buttons are drawn, before the main area This change will display both information. We should investigate how to actually detect if this is a render result or not as similar code is present in the `node_shader_buts_tex_environment_ex`.
