There is an error with the displayed "Last Message" on the main Forum page (Community/Forum through the topbar menu).

For example, as of this writing, the last post in the Arabic Language forum shows up in both the Arabic and Chinese forums; the last post in the English forum is repeated as the last French forum post; the last Japanese Language post shows up three times, in Nordic and Romanian languages.
This is the page where I am seeing the problem:
