Hue motion sensor 1 (5 items?)

Setup, Configuration and Use Beginners

I just added my first Hue Motion sensor
I use OH 3.2.0.M4.
After discovery openhab detects 5 items (see below). Is this correct?
I was expecting only the motion sensor 1

One more question.
Why is the formatting from Hue not working (number of decimals doesn’t change) and the same does work for z-wave.
Can someone advice how to solve this in the items file?
