That particular install is on a VPS with WPMU Dev which is not shared hosting, they use a managed version of Digital Ocean droplets for each website.
Oddly, I disabled all other plugins, the information was reported correctly, and after I activated the other plugins one by one the information was still being reported correctly.
If it happens again I will try disabling one by one until the error is corrected to get a better idea of which plugin could be causing the problem.
