AutoVoice Ok google Ok does not work

Hello,
I created a profile for my home automation, open the shutters with Autovoice.
When I say: "ok Google, say to Autovoice: close the shutter" I have a popup that shows me that the message was intercepted by autovoice. But the task does not work.
When I use recognize and say; "close the shutter" it works very well.
Do you have an idea.
I have also tried an alternatice with autoshare but I can't do it at all.
PS: sorry for my English.
Thank you.
