Technically a duplicate of a 10 year old report: viewtopic.php?p=550749, was marked as not a bug, but I still think this should be fixed.

Steps to reproduce:

1. Have a vehicle (tank, spidertron) with equipment
2. Have it in your hand and click on the quickbar to set quickbar item be that vehicle
3. Place vehicle from quickbar to ground
4. It disappears from the quickbar

Also, while vehicle is still in the inventory, the quickbar icon doesnt say the number of vehicles you have.

BUT, if you put the vehicle onto quickbar by clicking on the quickbar first and selecting it from the menu instead, then it no longer disappears when you place it, and the number is shown just like if it didnt have equipment. Which is the expected behavior for me.

If it has been reported before, do not report it again.

It remains being Not a bug. There are 2 different states of the quickbar, one is when you set quickbar to represent any item of given type, in this case it will show you how many items you have in your inventory. Second is when quickbar points at a specific item which takes place when item is special one with data. When you build the vehicle all the settings including grid are taken from the specific item instance and the item is gone meaning the quickbar slot is cleared as it is no longer able to show a specific item instance.
