Imported *.dxf has extra hatches

building volumes.dxf (19.6 MB)

building volumes.dwg (5.2 MB)

Dear community,

Whenever I import this file in rhino 7 it produces 35751 hatches instead of the 35725 objects in the dxf file. If I convert it to a dwg, I run into the same problem. The excess of hatches is shifting the heightdata (in my csv) which I aim to connect in grasshopper, as to create building volumes. Does someone know why these extra geometries are created and how to solve this?

Help would be much appreciated,
