Mess up after Relia theme update

Hi,
as wrote in the topic title, after the last theme update I had half of the website messed up, I was able to fix everything out of a weird issue, on the home page under the slider section there is a blog post saying no results found, I am in an urgency for removing it, I tried adding some strings found online in the CSS but no changes, any help would be really appreciated, the home page is this:

Thanks in advance
