Bloco de caminho de grama

Hello, when using version 1.15 release, it with a bug in the grass block (grass path), because when you pass it when climbing a  Cobblestone Stairs it blocks me, as if it had an invisible wall that blocked me ( this in the plains biome); Another fact that occurred last, was when entering a village in the mountain biome, I came across a similar bug, but the difference is that there are no stair like plain and when I climb a block it seems that it has a force that pushes me out of the block. I have attached the image of the block in question below.

Finally, I would like to know if when to open a topic here, I can write in Portuguese or if you prefer in English?
