No content displaing in Sidebar on Main Blog Page

Hi

I wonder if you can help me out – I’ve built a blog using the ‘advamced layout builder’ and all appears ok on both the single poat and archive pages but for some strange reason I cannot get the sidebar content to display in the blog homepage (the sidebar is clearly present)?

Any hints/tips or if someone could take a quick look it would be appreciated. The link is: https://goldcross-training.co.uk/news/

Thanks in anticipation.
