Box Office Mojo
The Box Office Mojo website underwent an overhaul in 2019, resulting in several bugs that led to errors in charts and grosses in the database. The full extent of the issue is explained at the IMDb Customer Community boards (archive). The second and third problems on that list (the incorrect release years and the algorithmic error in the weekend charts) have been addressed to the best of our knowledge.

However the first problem (the double counting of some release grosses) still remains and will need to be fixed manually. To take Harry Potter and the Deathly Hallows – Part 1 as an example, the 2010 New Zealand gross is included again in the 2016 reissue gross and the 2010 Spain gross is included again in 2020 reissue gross. This means that these two grosses are counted twice (once in the original gross and again in the reissue gross), and thus artificially inflating the lifetime gross of the film.

This seems to be a common error affecting a whole slew of films that have had re-releases. The goal is to catalog the grosses that have been double-counted in the table below and liaise with Box Office Mojo staff to correct the figures. This venture is of mutual benefit to both Wikipedia and Box Office Mojo.
