6.2.2 keeps trying to ‘upgrade’ to 4.6.1

Hi folks – my 6.2.2 site’s upgrade process is somehow trying to upgrade to 4.6.1. Eg, my site’s upgrade home section shows the upgrades available, and on the upgrade WP portion of the page, the button to upgrade literally says ‘upgrade to 4.6.1’ – I tried previously, bfore noticing numerical designation and it totally broke the site, of course, I rolled back to 6.2.2, and while I know how to manually upgrade to 6.3, I would love to get some feedback on this oddity so it can be fixed. Any ideas, or places / logs / pages to check?
