How to change Welding Standard from ISO to AWS in 3DEXPERIENCE CATIA

hello all,
anyone has an idea how to change Welding Standard from ISO to AWS in 3DEX Catia V5? I tried to change the whole drafting standard to ANSI, but welding still seems to be ISO.

Else, how can I remove the "Dashed line" in the welding symbol when I have different welds on different sides?

Please help
