Mods: no setup button

I have Civ5 G&K updte 1.01.1.705. I don't know if this has been mentioned yet or not but, here it is: after I download new mods and then check activate them I hit the next button to activate them. When the next screen comes up I go to single player and when the next screen comes up, all I have (load and advanced settings, no setup button). Is there a fix for this?
