On "profile", "Recent Games" lists first ("pinned" on top) a dozen very old games against one bot.

As the title says: On the android app, when I go to Profile, the "Recent Games" section is "flooded" by a dozen of very old games against one bot ("Antonio Bot") which seem like "pinned" to the top of the list ; also, when I click on the section to list all, these come first in the list, before all other (more recent) completed games (as well against bots as humans).

It does not happen on the web site. (I can supply screenshots if useful.)

How can I get rid of this?

Try clearing your app cache, and uninstalling and reinstalling if that doesn't work.

Though it's possible there's a bug with sorting and saved bot games.

I don't think it's related to app cache, IIRC these games were already obsolete when I reinstalled the app to switch over to the beta version, not so long ago.

It's possible that I may have saved the analysis back then (not sure, though), but now as I check they're no more in my list of "Saved analysis".
