neotree strange gray background with astrovim

[lunemec]

Hello, I'm using astrovim, and for some reason the neotree with this theme changes color after re-opening the neotree.

When I initially open empty nvim, and open tree, it has correct color on the background. But on any opening of file in the neotree or any other action that causes the neotree to reopen some folders, it changes the bg to this strange gray.

I don't know why, or if its bug or feature, nor in which plugin. Any ideas?

I'm seeing the same gray background with Neotree and LazyVim except that the gray background is there when I first open it.
