Problem positioning icons in floorplan/inkscape

Good morning,
I’m making an incredible effort to place the icons on the floorplan.
To put them in the desired point, I have to put the rectangle in inkscape in a totally different position !!
For the rest it works perfectly, but this problem complicates my life a lot.
Why

Thanks, Alberto

Resolved.
All ok !!
I had some problems in the svg
