some sloping components are missing?

[mushroom0V0]

HI~We encountered some problems. Some oblique components could not be displayed. The model should look like this:

but, after I imported my IFC file,some sloping components on the edge are not shown(purple arrowheads), while others were no problem(red arrowhead).

And this is the ifc file:
test.zip
What's the reason, please? How can I deal with it?
(Wow,This is the first time I write a letter to a real person in English, not in the English writing practice.Hope that I don't have too many grammatical mistakes(*￣︶￣))

The IfcEllipse objects were losing their position in translation. This has now been fixed and will be in the 1.9.94 release.

I’m thrilled to hear that !!! Now we are using the version released in May,maybe earlier~if we update it directly, will there be some compatibility problems?

[rubendel]

Yes most probably, in most cases easiest will be to remove your database, remember you are on a development version.
