Wix pro gallery button doesn't show up

I have added button to wix pro gallery to my website home page. When we open my live website on any browser it shows buttons on wix gallery images. However if go to any other webpage of my website and then come back to home page it doesn’t show button on wix pro gallery. Why button doesn’t show up every time. Does wix pro doesn’t render all of it. How can I force wix pro gallery to show button every time I go back to main/home page of my website?
