Definitely shouldn't be working that way. As you have a couple of items going on with the Versa - would you be willing to speak with our engineer? His name is Trent and his email is email@example.com.
Right away here are my thoughts:
Bottle coming out of the cage - thinking a spacer is missing underneath the rear bottle cage screw. Reason being, the bottle should lock in place so that in order to get it out you have to twist and pull. If it is just slipping out, it is not catching.
Lid not closing tightly - this is a 1st for me. Could be an issue with the lid or the bottle here. Would need an image to figure out what is happening there.
Hopefully you give us the opportunity to make things better for you!
