The data is out of date. What is happening is the identifier stored in the schema, for instance like here
no longer represents the same taxon as when it was entered. It no longer represents the same taxon as when entered due to changes in the taxonomic backbone at either iNat or GBIF.
That element has to be entered in order for any GBIF data to show. If it is not entered, no GBIF layer will display, if it is entered, but is outdated, incorrect data will appear.
As far as I am aware, there is no process to to revert anything here, at least not on the iNat side. I don’t believe any automated process interacts with the data in schemas.
I can’t imagine any way GBIF is going to tolerate a bot or process constantly hammering their site to check for changes or mismatches on the identifiers.
