RO2 Problems with changing the map

Hi all.Yesterday we played with GULAG a friendly war on the EU #1 TWI ladder server.Both leaders of clans couldn't change the map by writing in chat $AdminChangeMap TE-Barracks.After we wrote this in chat the message appeared.(see screen)

Please tell us what we did wrong or maybe this option was off on this server?

But I tryed to do it on EU # 2 and I had the same problem as the leader form GULAG.

Thanks
