Some birdtrack records which were recently added/uploaded are showing some species seen going back several years ago and as far back as 1980 for one of them! I have not verified any of these (just ignored them for the moment) and assume this is a glitch in the system? Seems odd for some very old records to appear on the system that were uploaded this or last year.

'old' recent records
Had a look at the samples, they were updated in 2022 and showing recorded in 1980. ID No. 28948628, 28948627 and 28886354 being some examples.
Could you give us the record IDs for one or two examples? We can then check with BTO.
