Edit "HomepageText" topic

Hi,
I'm making a site in nopcommerce with theme "Default Clean".
Can you explain why if I edit the .cshtml file of the topics "HomepageText", I can only see the changes by opening the topics and not on the home page where it is visible?
I leave attached photos to make the question as clear as possible.
Thanks everyone.

Hi,
if you edit topicdetails.cshtml you see change only in topic page and not in other page, homepage in your case.

try edit Presentation/Nop.Web/Views/Home/Index.cshtml

I have reported number bugs to their ticket system to have them fixed.  Their css responded very poorly to things that bootstrap achieves with ease..  I am happy to share with you some of the bugs I have reported.
