Please help me out from this issue? My site fetches blog page description & tit

[Roshiniverve]

Here is my website https://www.auzrentalcars.com/

It just fetches blog page title and description to the home page, because the developer has used the theme options plugin for homepage & custom widget in the blog page. 

If I make any changes in homepage it won't make any issue, but if I did any changes on the blog page, the same title and description have reflected in my home page.

So the problem is Blog page and home page fetches same title & description in the search result, So I can't rank any keywords for my home page.
