LayerBuilder issue in Lumerical version 2020 R2.4

Dear Sir or Madam,

I am experiencing an issue while trying to upload the GDS file shown in the image below on the LayerBuilder utilities when the sidewall angle is <=86deg and the sidewall angle position reference is set to Middle. All the detailed settings are in the attached screenshot below.

It seems that I get a warning message saying that the sidewall angle is too small and as a result of it the planar solid from the imported polygon cannot be generated. It looks however that the minimum dimension of the attached GDS should allow the creation of the planar solid so I am a little confused on what the error might be.

May I ask what is causing this behavior in details and whether there is any possible workaround to upload the GDS file with sidewall angles below 86 deg?

I tried to attach the corresponding GDS and .fsp files as well but the system did not allow me to do so. Please let me know if there is a way to attach the above mentioned files if needed as I would gladly do so.

Best regards,
