@n1siva I moved your post here because this issue is slightly different from the one with Melagiris in your other post.
Melagiris isn’t an official district, so it can be modified by curators. The official districts are level 2 places (see Scott’s link above) imported from GADM and can only be modified by staff.
So someone on staff needs to change “AP” in each district’s Display Name to “TN”.
There’s another issue that might or might not be related – some of the Tamil Nadu districts have null slugs, causing null About links in the header search (Coimbatore, Chennai, Karur, maybe more).
