Unwanted authomatic update of pages shown on the front page

https://www.technosource.net/3Dprinting/

Hello all.
I am updating frequently the pages and at the top of the main page (both horizontally and vertically) the site indicates those changes
(as tv programs, cloud computing, iso, etc)and I do not want this to happen.
Please check also https://snag.gy/RSP1E.jpg

Can someone help?
Please note that I work on a Twenty Fourteen Child theme page

Thanks a lot !!!
