When use callback - compose work strange in interaction

[TruesSpeak]

Hello. In my case I set in interaction
set_callback :execute, :after, :pay_prepayment or set_callback :execute, :after, -> { pay_prepayment }
And have 4 compose() with another interactions. When callback is commented everything is ok.
When callback is work, I have

Interaction that I call at the screen - have validation, that fails.
Have idea how to fix that?
