Tilemap having a multiply blending mode for some reason?

I’m using a tilemap object for the map (made it with LDtk)
It has 3 layers:

  1. Background tiles
  2. Ground tiles
  3. Foreground tiles

Background tiles and ground tiles work fine, but for some reason, when I get close any foreground tiles, this happens:

(When I get near, this happens)

I mean, I guess the only reason that is possibly happening is because of the multiply effect of the water that is near this area, but why and how the blending mode of the water affects the tilemap? And also, why does the blending mode activates all of the sudden when I’m in a certain area?

Any help is appreciated, please ;-;

Edit: I tried deleting the water and the blending didn’t happen, for some reason???
