Perfectly overlapping colliders result in only one of them being detected by Unity.Physics raycasts

Is this normal behavior? I even have one collider as one layer, and another as another layer, and set up the raycast to detect only the first layer. In addition, I went to Edit->Project Settings-> Physics and unchecked the boxes so that each layer can only collide with itself (the raycast input's layer will be, for example, set to A when the collider it wants to detect is in layer A).

Edit: It appears that the problem is that if a GO with a collider and layer A is a child of another GO with a collider and layer B, only the parent GO with layer B will be detected by raycasts. The parent GO in this case has the ConvertToEntity script attached to it whereas the child does not. Any insight into this weird behavior?

Edit2: Fixed by changing ConvertAndInject to ConvertAndDestroy. Forgot that I have to do ConvertAndInject if I want children to be converted as well. Mods please remove if this post is non-informative
