Clarification on 'Warning: To many values of z. Using 2D polygons'

[e-manduchi]

Hello, I'm running baysor v0.6.2 to get a 3D segmentation for CosMx data, where I provide as prior the cells identified by CosMx. I am getting the below warning and therefore I only get joint polygons. Can you clarify what causes this? Thank you
