Variables are no longer showing after updateing polyscope from 5.11 to 5.13

Hello,

After updating Polyscope software from 5.11 to 5.13, the global variables created in our URScript are no longer showing in the “Run” tab of Polyscope. Our URcap and program are still functional other than that. We build our URcap using the URCap API v1.3.0, but even when using the API v1.13.0, the variables are not showing.
It is reproducible on the simulator: the same URCap will display the variables on the URSim of Polyscope 5.11, but not 5.13.
Is this a regression of the 5.13 Polyscope?

Best regards.
