Problem with scavenger ascendancy.

I recently tried trying new things on my character and refunded an ancestry point but now I can't put it back in place.

I have the necessary refund points but I can't remove the small node that is crossed out with an x ​​in the image

Have you tried refunding the extra point on your tree that you were granted when you allocated the X node in your image?

yes i did but it doesn´t work
