Stick both sidebars

Hi, I have two sidebars and I apply the plugin as described. Result: The right sidebar sticks perfectly. The left one does not stick, but disappears (after scrolling). Any idea? In the plugin settings, I have e.g. “#left-sidebar, #right-sidebar” (same result with classes). The elements are detected as the disappearing shows. The elements are as follows: ” <aside id=”left-sidebar” class=”sidebar-container widget-area sidebar-secondary” itemscope=”itemscope” itemtype=” https://schema.org/WPSideBar” ; role=”complementary” aria-label=”Sekundäre Seitenleiste” style=””> … </aside> <aside id=”right-sidebar” class=”sidebar-container widget-area sidebar-primary” itemscope=”itemscope” itemtype=” https://schema.org/WPSideBar” ; role=”complementary” aria-label=”Primäre Seitenleiste” style=””> … </aside> ” ps: For some unknown reasons to me, the right-sidebar is classified as primary sidbar, if that plays any role. I haven’t find out how to change that. Hello, Kindly share that page URL where you facing the issue and a snapshot of your sticky elements settings.
