A few issues with highend theme

I have had the theme for a few weeks and love it. I am just seeing a few issues that I do not know how to correct.

1) Just recently my live preview isn’t showing the changes I want to see. The only way it will show me the changes is if I click “update” to make the changes go live. Is there a way to fix it so I can see if I like the changes before they go live?

2) I have two LayerSliders WP on my website (one at the bottom of my landing page and one at the top of my blog page) but the mobile version does not display either slide correctly (it shows the slide without the words on the landing page) and it does not shrink either of them to fit the width of the phone. Also when you look at an individual blog post on a mobile, the links to make a comment are askew ~ can they be fixed so they will line up correctly?

3) I cannot get the blog grid posts to line up evenly on the blog page. I have the “crop featured photo” selected so that it will automatically resize the images, but they are not lining up symmetrically as shown in your demo. Also, I have the boxes checked to show the author, category and date, but only the date is showing up on the homepage.

4) I would like the option of having a sticky post without the little thumbtack showing up on the blog page. Is there a code to delete that icon?

Thank you!
