Can't save carousel with action Postback in DB

Hi everyone. Hope you´re great!

I wanted to save in my DB the 5 last messages, but the problem is carousels have no name and are all listed as “Carousel:undefined” so i get the error Cannot read property 'split' of undefined. But i have this problem just for action Postback, the action OPEN URL works good.
I am using version 12_18_0.
