Thanks for replies!!
Yes I tried to put tilemap on another layer, but it doesn't help - it still gets chosen whenever I click on screen.
(Also if I move tilemap to layer below, then all that's drawn on it disappears from creeen, at all. And still gets chosen whenever I click on screen).
I am almost sure everyone have same issue because tilemap sort of covers screen by default if I am right. So it will appear every time you click everywhere on screen which I find pretty annoying.
Should be a way to bypass it no...
