Hello, community.

I am currently doing a self‑study to build a simulation using ARC. During the process, I encountered an issue related to the Arc Profile settings.

As shown in the video I recorded, the Arc Profile should allow selecting ArcStart1 for Start, ArcStart1 for Weld, and ArcEnd1 for End. However, in my case, all the checkboxes toggle together, and I am unable to enable or disable them individually.

I would like to know whether I am misunderstanding how the Arc function is supposed to work, or if this behavior might be a bug.

Thank you in advance.
