That certainly sounds like a strange issue you're having with the Messenger and Twitter sales channels, and it's not something I've seen before. Without looking at your store directly, it's hard to say what the issue might be.
However, I've sent an email to the address listed on file for your store so that we can get to the bottom of this!
Hope that helps. :)
