The issues will be quick hacked (fixed if you wish) running the following SQL update statement on the Data.StackExchange database by someone with full database access.
That sites table does get/should be populated now and then (on changes) from a different source so maybe it is wiser to fix that instead.
The script fixes Writing, CogSci and CodeGolf
I have tested below script here
Use [Data.StackExchange]
-- writing
update Sites
set BadgeIconUrl = 'https://cdn.sstatic.net/Sites/writing/img/apple-touch-icon.png'
, ImageUrl = 'https://cdn.sstatic.net/Sites/writing/img/logo.png'
, IconUrl = 'https://cdn.sstatic.net/Sites/writing/img/icon-16.png'
, Longname = 'Writing'
where Id = 84
-- writing Meta
update Sites
set BadgeIconUrl = 'https://cdn.sstatic.net/Sites/writingmeta/img/apple-touch-icon.png'
, ImageUrl = 'https://cdn.sstatic.net/Sites/writingmeta/img/logo.png'
, IconUrl = 'https://cdn.sstatic.net/Sites/writingmeta/img/icon-16.png'
, Longname = 'Writing Meta'
where Id = 85
-- CosSci
update Sites

where Id = 147
-- CodeGolf
update Sites

where Id = 92
