Olivero Theme - Sidebar is not Floating / Sticky anymore

Problem/Motivation

Olivero Theme - Sidebar is not Floating / Sticky anymore, when I scroll the whole page down the sidebar is also scrolled/pushed upward fully (just like a notmal page), no sticky features at all.

According to some drupal 9/10 web example which I have seen , the SIDEBAR Block should have a sticky / floating characteristics. Although I myself have never really notice that this feature exists (on my hoster Drupal Installations (which is usring CPanel&Softaculous) since D10 was officially released on 2022 Dec
