Illustrator 2021 (25.1) does not retain its original size when the .dxf file is opened. (DXF Bug)

Good day,

a while ago, a colleague warned me that when she tried to open a DXF file in Illustrator 2021 (25.1), and even if it was set to "Keep original size" correctly, the size would not be preserved but it would be reduced in some way.

The old version of Illustrator 2020 (24.3) works correctly. More

I'm also attaching a sample file where you can verify it.

This error is crucial for our work, please fix it quickly.
