The reply button doesn't work

Hello guys. I’m experiencing some problems with segmenting. The reply option doesn’t work properly. When I click on the segmented part and then the reply button, the green line doesn’t move and it doesn’t allow me to reply that part which is really troublesome - if I can’t reply it, I can’t segment it properly.

Is this temporary, has anyone had a similar problem? It’s driving me crazy :slight_smile: Thanks in advance
