Hi. Looks like the attached EXR was rendered using 19.0.383. There was a change in 19.0.416 to apply prefixes to channel naming in multi-part EXR images to improve compatibility with Nuke (which has problem reading multi-part EXRs if there are multiple parts that have same channel names). Please try rendering with 19.0.416 or newer.
