Unable to View Full Wireframe in AI Sitemap Editor

Hello, After I first put in my description then allow AI to generate my sitemap and wireframe, I select wireframe to modify, but can only see the landing page at 25% view zoomed out. When I take to 50% view or closer to see better, it only shows the center of the page (the additional pages) and the land page is cut off. There no left/right scroll bar, how can I be at standard 100% view and see the landing page for editing if I have other pages? Thanks
