table properties window ignores unique constraints

[kor3k]

Describe the bug

the table properties window does not show unique constraints.
(right click table -> properties -> constraints -> unique)
no unique index is shown here.

but table definitely has them, as "CREATE script" writes them correctly
(right click table -> scripts -> CREATE script)
indeed includes unique index definition.
