Report looks fine to me
A small uptick in Fe could simply be the result of a bit of chelation with some of the Group V base stocks potentially in use with this product. These are parts per million, these minute variances cannot be used to gauge relative performance to other lubricants, the tool simply lacks the resolution.
Generally, as @Rand noted, the idea is to do several OCI's to gauge what's "normal" for that particular lubricant in that piece of equipment. Trying to compare lubricants to each other based on that data is chasing your tail because each will have its own "signature" that does not directly translate into actual wear characteristics, as there are numerous other mechanisms in play, particularly when you go from one product to another with potentially wildly different additive packages.
