May I know why are you using Q3D for importing GDS file instead of HFSS 3D Layout?
I suggest HFSS 3D Layout is the best choice for your case as your design is multilayered. If you are new to HFSS 3D Layout then you can go through the 3D Layout help - Ansys Electronics 2023 R1 - Welcome to HFSS Help and "getting started guides" - Ansys Electronics 2023 R1 - Welcome to HFSS 3D Layout Help.
