How to use VBA to export SOLIDWORKS model to Parasolid x t format with label

CS 2021-08-16 SOLIDWORKS News & Info

I have a VBA macro which uses .SaveAs3 (recorded macro in SOLIDWORKS) to export the .x_t format of the model. However this will not successfully transfer the labels on the model to the Parasolid file when I call the VBA through batch mode. When I export the file by hand/GUI, the labels in the .x_t file were preserved.

What have I don't wrong ? Anything else I need to do if I want to us VBA in batch mode to do this ?
