Rhino8 "Content Cache" issue, and File export problem with Elefront V5.15

I need to export several shop drawings from a tree structure, but I am unable to export them. There seems to be an issue with my definition, but I can’t identify the problem.

Each tree branch contains geometry, dimensions, and text entities with adjusted user attributes (such as color, linetypes, line thickness, dimension text size, arrow type and size, etc.) related to the drawings.
Using the Rhino 8 Grasshopper (GH) application, I baked the content of the branches into Rhino8 using a layer structure. Each drawing has a mother layer, and the drawing entities are baked onto the appropriate child layers. (See the attached RH8 file)

Unfortunately, the export is unsuccessful. The Elefront “Export Genetic” node creates the DXF files, but these files remain empty.

2D_Drawing_Dxf_Export_Issue.3dm (2.8 MB)
DXF_Elefront_issue.gh (11.9 KB)

I welcome any suggestions that can help solve the issue.
Thank you in advance for the help!
