I've changed this translation from Kaca Utama to Kaca Pokok, which is more proper considering Utama means "Noble" while Pokok means "Main" in Javanese. However, my change doesn't take effect on jv.wikipedia.org, but it does in jv.wiktionary.org. What can I do to correct this problem? Thank you in advance.
