how to remove index.php/about-hot-academy/template

hi hellpe please
I bought the hot_app template and I want to know, if it is possible to remove "about-hot-academy"

www.mysite.com/index.php/about-hot-academy/template/my alias

i change alias but that "about-hot-academy" is is allways in middle of my www field

remove or rename but where????

That is menu item alias of "Features" menu item. But you don't see it in menu item settings, you have to change menu item type to single article to show up, then set it and then return type to external url

but how
please step by step
i dont know where to strat or what to do

i find solution thanks
