Why do the instances not appear in the right place

[_iris]

The position of the instances is not where the landscape is, why is that

also when I change the collection info to original they go to the original position

Most likely its the coordinates. Try to apply location to your base mesh. Or just use Original.

thanks that fixed it

If you apply your positions, your mesh ll be far away from the origin. So if you use mirrors or modifiers based on origin with your instances… you ll be f…cked.
Better reset your instance position to 0.0.0 with alt+g
