[Vantage Theme] Static Post Page NOT working

Hi. I am using Vantage Theme (v1.2.3) on WordPress 4.0. I have successfully created a custom Home page using the Page Builder. Now I am trying to do the same for my posts.
I created and published a new page (named it Posts). I simply inserted a new row, split it into 2/3 and 1/3 parts, included widget “Post Content” on the 2/3 part and a custom “Text” widget on the 1/3 part, in order to test that it’s working.
Then, I went through Appearance->Customize->Static Front Page->Posts Page and set “Posts” as the default page for displaying posts but this is not working. I still see the post’s content on the full page’s width and the customer text widget is nowhere. I also tried going through Settings->Reading and the Posts Page was properly defined there as well.

Please help me here. I don’t know what else to try or test. I tried changing the Permalinks to default with no luck (saw it somewhere as a suggestion).
