There's caching so they take a while to update. Constantly gets on my nerves when editing templates. :( S(talk) 23:38, March 4, 2016 (UTC)
Add ?action=purge to the end of the address if you want to force the server to rebuild the page so you can see the template on a page in its most recent version. The delay is normal and if you do nothing it will update on its own eventually. 5-xTalk 12:26, March 5, 2016 (UTC)
