Rise: Bullet points not changing colour with font

Hi there, I am producing a course with some blocks with a dark background with white font. 

My problem is, the bullet points refuse to turn white! They are staying black. I have tried to highlight right to left, exported text and reimported as unformatted text, built brand new blocks and keep having the same problem. 

I've attached a sample with the block in it. Can anyone help!?
