I don’t know much about this swap other than, based on the comments on the thread, processing for this swap is still in progress so not all observations have been processed yet. This is a particularly large taxon swap affecting many thousands of observations. Affected observations are not immediately updated and the change takes some time to complete, so there is a transition period where some observations are updated and others have not yet been updated. I’d recommend waiting a few days to let the processing finish - the one you say has not changed may still be in the queue to process
