Anchors and tag positions completely incorrect

Good morning to everybody,

I have some problems with my DWM1001. In particular I have a system with three anchors and one tag. I set the three anchors like an equilateral triangle to which I manually assigned the coordinates. However, when I go to read the coordinates of the tag, they are completely wrong. How can I solve it? I’ve also already tried resetting everything and starting again but it still gives me the same problem. I also tried the auto positioning by defining an initiator and then ordering the other anchors counterclockwise, but the application sets the coordinates completely wrong, even by a few meters!! How do I solve it? thank you all
