Pale Oak Signs do not have extended rendering. I just installed the mod and noticed that my pale oak signs would disappear at the normal render distance, however, the mod would extend all my other signs. The mod is working, it just needs to be updated to include Pale Oak Signs.

Also, is there any chance this mod is ever going to get updated to work with banners?

I know it's a lot of work to update it so thank you for your continued effort!

Just came here to report the same issue lol
