I was trying to do a industrial smelter but when I try to distribute the ores in Hoppers to burn them in the furnaces, but something goes wrong, the ores doesn't distribute correctly, and I can't understand why, because the files related with  CollisionBox and the HitBox are exactly the same as the others of older versions of Minecraft. Probably is related with those because also the ores can be sent to another minecart that isn't under the first minecart but it is next to the other.

Here's a video of how to replicate the bug.

I am not sure at all but I think that this bug appears not until the beta versions 1.11.

I going to do a research for the exact version when this bug appears.

My phone is a GoMobile 504.

Sorry for my bad English .

Thanks for your attention and work.
