I think you are using $router.push in the created or mounted hook of your route component for /items/:itemID.
When you use $router.push, a new item in history stack gets created. So your history stack now looks as follows:
/list >> /items/:itemID >> /items/:itemID/Property1
As the back button generally takes you to the previous entry in your history stack, it takes you to /items/:itemID as expected.
To avoid this, you may use $router.replace instead of $router.push as explained here:
https://router.vuejs.org/en/essentials/navigation.html
Quoted from the page above:
router.replace(location)
It acts like
router.push, the only difference is that it navigates without pushing a new history entry, as its name suggests – it replaces the current entry.
If you use $router.replace, your history stack now will be:
/list >> /items/:itemID/Property1
Now if you hit the back button, you will end up in /list.
