Two lists' icons not displaying as they should

I think the icons of the official lists :
do not appear as they are meant to since the central circle is bigger and the background is black. For this reason, they appear out of place in the “progress” page.
If I remember correctly, this was already the case for some other official lists but the problem was corrected rather quick ; here, it has been lingering for quite some time, so I am beginning to wonder if this is intentional.
Cheers, looking forward for an official answer,

Thanks for reporting this. The icons have been fixed. Might need to hard refresh (ctrl+f5) the page before they’re displayed.

Fixed indeed. Perfect !
