Custom Game w/ Bots

For some reason when I go to gank another lane (Playing Akali mid and going either bot or top to get more kills) I get there get the kills and then head back to my lane, but then one of the bots I'm playing with will come to mid and pretend like I'm not there so in doing so an enemy bot also comes to mid and helps out their mid laner, why does this keep happening? I just want them to go back to their lanes!
