When developing a chatbot using node.js and Facebook Messenger templates, there is a problem in the result of carrousel of generic models when testing the bot with the Facebook web interface. The buttons of each item in the carrousel aren't shown all of them. For exemple in the image attached in stead of 2 buttons there is only one button in each item. (In an other example no one of the buttons is shown). However, the result is completely normal when testing the bot with the Messenger mobile application and the web interface of Messenger. Is the problem with the Facebook web interface ? If not what could be the issue?
The image attached represents the result of testing bot with: The Facebook web interface (the issue), the Messenger web interface and the Messenger mobile application.
