Appearance of non-existing edges when importing SOLIDWORKS CAD files to COMSOL

I'm currently using Solidworks 2022-23 for my CAD modelling. As you can see in the pictures below, there is no edges on the top when I sketch the shape in solidworks. But an edge emerged on the top of the shape when import the CAD file to COMSOL.

Does anyone has a solution to this? I've tried to import STEP file rather than SLDPRT file, but the issue still exsit.

Is the added edge problematic in your solution? There are a number of approaches you could take, including: * building the geometry in Comsol as the geometry seems quite simple, (which will allow you to parameterise your model) * Using virtual operations to ignore the edge or form composite faces to effectively eliminate that edge for mesh/physics. * Ignoring the additional edge

In my experience this type of thing is common when importing CAD and can usually be ignored.
