Eraser tok becomes latest brush tool

[Ann-Charlotte Berlin]

Hi!

I hav a problem with brush tool (especially when I have used different star brush), when I work with making of a card or ad etc. 
After using the brushes the eraser tool no longer erases, it is a brush! 
 

Why, and how, do I fix it?

Hi @Ann-Charlotte Berlin,
Welcome to Affinity Forums
Do you mind recording a video of the whole application window with the Brushes, Colour and Layers panels visible, so we can see what's going on?
From your description alone is difficult to guess what might be happening. Thank you.
