EEschema, changing color of sheet border in preferences only affect old sheets, and not newly added sheets.

Description

Wanted a different color on my sheet-symbols frame. Changed in preferences/color, but worked only on an old sheet, not on a recently added sheet.

I did first changed the width on that from 0.152mm (nice number) to 0.3mm, but then realized a different color would be better. But this newly added sheet wont budge, regardless i changed back to 0.152
