batch create for add users ever add them to network admin instead site that I choose

I setup multisite network.

I have below sites:

ciberanika.com
cuentos-terror-kruela.ciberanika.com
leyendas.urbanas-kruela.ciberanika.com

etc....

first column of xls I wrote "ciberanika.com" and title "Ciberanika", rest of columns with users etc... but instead add users to ciberanika.com add users to admin network, if I try diferent options like null or nothing just create new blogs.

How I can upload my users to ciberanika.com for later sincronice with rest of subdomains?
