THEME BLOG TEMPLATE – DISPLAY ERRORS

Hi!

Please, I need your help. I am using the Blog Grid Template (HBTheme) on my blog page:
https://ewetjourney.com/miblog/
(go all the way down)

But I have these problems:
1. Even though I created a unique category “blog” for the posts I want to be displayed here, the page will display all of them. Why? I have tried with other categories, but still, it will display all of them.
2. There is a big gap between the image and the title of the blog post. How to eliminate that?
3. There is no excerpt, even though it is set up to show it. Why?
I have attached an image for better understanding.
There is one post, which says ” quote post”, that from the examples I guess. It´s the only one, which is working properly…
Thanks in advance,
Ivette
