Why does my thrower throw out buckets at Minecraft?

Ca
- in Launchers

I play on the switch Minecraft and wanted to replicate the cow farm of LarsLP. This uses two launchers to create a source of water and lava. I copied everything 1: 1. In the video, only a lava or a water source is generated for a short time. Then the launcher takes back the contents of each bucket. Unfortunately, both launcher throw at me the bucket at the touch of a button only completely. And yes, I'm sure that I've installed launcher and no donor. Does anyone know advice?

I know only with the Java version, but show the launcher on air or blocks? If you point directly to blocks it could be because of it:-)

The throwers have both air in front of them.

Then I do not know what it can be, I'm sorry: - /

At the most you can see if you are playing in the right version, with Java everything changes a lot every now and then ;-)
