New involved physical link in a physical path, color update issue

Hello,

When I update a physical path with a new involved physical link (in a PPD), sometimes the color of the physical path does not apply to the new involved physical link in the PAB… Even if i refresh, or if i undisplay the diagram styler…
I feel that sometimes, the physical link color remains the one of the physical link and not the one of the physical path…
Do you have any ideas on how to treat this please ?
Thanks,
edgar
