Website is defaulting to blog posts, instead of front-page.php

Hello

sorry for duplicate post, but can not edit or delete it!

I installed the Greenr theme today and all was working lovely. The home-page has a slider and buttons on it..

Go back to update some pages this afternoon, and the website is defaulting to blogposts instead of front page..

Can anyone help with the css so it stops bypassing the home-page please?
