Homepage duplicates image in column to left or right at full height

Hello All, I have checked your instructions and theme FAQs. The user Randall Hartman seems to have had the same issue but the solution was not included in the dialogue. I am using the latest theme version. On my homepage beneath the featured slider I am using a single column layout. The image at the bottom of the column is replicated to the left of the column. The replicated image is a narrow centre crop at full page height. When I go to customising>theme options>hero content, which is enabled on the homepage, the type is page, page is homepage. Using the content alignment button I can put the replicated image to the left or right of the column. When I hover over the block it appears to be a hyperlink. Using Inspect element in the browser it is called the 'cover link. here is the code line; I am using Safari but get the same issue in a Chrome based browser and when using an In Private window. The site is still being developed but I can send screenshots for clarification. Many Thanks Gary
