Note the status for this value are listed below, as well as what I believe their mapping to Orion status is from memory. In your UnDP above it does in fact appear that you are seeing the "nonCritical(4)" status which maps to a "Warning" condition in Orion. This would explain the yellow bars you are seeing in the availability resource.
