New user, just imported from Roam. Not sure this looks right

I am a Roam user and am testing out Obsidian. I loaded it up, and imported Roam, following the instructions I’ve read. But I’m finding the left sidebar to be really messy, and am wondering if this is what is supposed to be. It is showing all my notes, thousands of them as I continue to page through it. It includes all my notes, including all my Daily Notes.

I’m attaching a screenshot of how it looks. Does this look right? Seems wrong to me.

Apparently there is no support here. I’m going to use logseq.
