z index problem on group page (buddypress)

Hi, I'm having trouble on BuddyPress group pages. The avatar image is superimposed on the main menu. Attached image

The main menu code looks something like this:

@media(min-width: 769px) {
    .inside-header>.site-branding,
    .inside-header>.navigation-branding,
    .inside-header>.site-logo,
    .site-branding-container,
    #site-navigation .navigation-branding .site-logo {
        position: absolute;
        
        left: 50%;
        transform: translateX(-50%);
        z-index: 1000 !important;
    }
    
    #site-navigation {
        
        display: flex;
    }

I can't think of too many ideas, from the way I understand it, it shouldn't happen

Thanks !
