Live permids that recently disappeared

The following permids recently disappeared from the bulk files (they are not in OpenPermID-bulk-quote-20200927_044508.ntriples.gz), though they used to be there. They are still alive and kicking according to other Refinitiv products, so I don't think they should have been deleted.

The last one is particularly amusing, as it is the London stock exchange's self-listing! Can you please investigate.
