Disabled theme branding is shown in local configuration

I have 2 themes in my Studio project (test_solen_nx):

• one old theme called "global_Branding",
• on new theme created today, called "test".

"test" is my default theme, and is not disabled in theme branding.
"global_Branding" is disabled in theme branding and is of course not my default theme.

When I go in the local configuration of my instance default domain (or workspace or whatever), I see a theme called "test_solen_nx" and not my "test" theme. But if I select it, it still displays my default theme and the global_Branding.

Restarting my server doesn't change this behavior.
