Stp ap214 syntax error

Hello,

My version fo zw3d is 2026 sp1. I try to export assembly in stp ap214. Every time I export some parts or assemblies to STP and trying opening in latest edrawings, I got missing parts. Assembly not showing completely. I found NIST step file analyzer, checking exported stp files. I got thousends syntax errors in stp files. And I found app CAD assistent. When I open this stp files in CAD assistent , having no issues. There is a option in CAD assistent to save it in new STEP file ap214IS. After CAD assistent when I analyze step file , I get no syntax errors. With this ap214IS, when I open in edrawings, having no issues. It opens comletely, nothing is missing.
Can anybody advise me, what kind of version stp ap214 has zw3d ?
