Entity "mexA Pseudomonas (PseudoCAP:PA0425)" accepted by Noctua, but cannot apply annotations?

Entity "mexA Pseudomonas (PseudoCAP:PA0425)" is accepted by Noctua, but I cannot apply annotations?
every time I try, a red symbol appears next to the GO MF identifier.
mexA Pseudomonas (PseudoCAP:PA0425) is a synonym for Swiss-Prot / UniProt:P52477. Unfortunately, Noctua appears to not recognise P52477 either.

PseudoCAP doesn't provide a GPI in the datasets/yaml
https://github.com/geneontology/go-site/blob/master/metadata/datasets/pseudocap.yaml

Should we get the entities from UniProt?
