Millénaire mod wrong version

Hello, I recently created a forge server in 1.7.10. I put the Millénaire mod by going to the "mods" category of Aternos. The problem is that the villages that are supposed to be generated by the Millénaire mod do not spawn. The blocks that the mod adds are indeed loaded but the villages do not appear. I make my research and the Millénaire mod has two versions, a client, to play solo, and a server version. The server version must be installed on the server in order to function properly. But in your mod category, I get the impression that it puts the client version on the server ... will it be possible to download the correct version? Thank you and have a good day!
