I should have paid more attention when you mentioned "UV issue." It is not a problem with your passports. It is a problem with TSO training. Or actually not, read on.

There are a few ways a document might pass CAT verification just fine but still be fraudulent. UV light is used to reveal certain security features of the document which help authenticate the document separate from the automated authentication. Under international agreement (ICAO 9303), MRTDs must be produced with standard security features. But countries may also include non-standard features and I expect the Kingdom has incorporated some non-standard OVI and/or OVD features in their newer passports. In your case, the TSO saw unexpected security features under the UV light and additional scrutiny was required. So, this was a training moment.

To be fair, with more 200+ countries issuing a variety of travel documents, each featuring varying security features, it is easy understand how TSOs might not be familiar with all of the features on a document, especially if it was a recently issued document with updated or new security features.

You need to do nothing. In time, the document checkers will catch up to the documents in use.
