Windows 11 Update Icons Not Stacked

Recent Windows 11 March 2023 update. Once update was complete, the icons in my system tray (bottom right icons where clock is) are no longer stacked, they all display horizontally instead of stacked. I've tried everything including checking the registry key in the registry (regedit), which is set to 2 which means stack the icons in the system tray but they all still display horizontally. I do not know if this is a Start 11 issue or a Windows 11 issue. Any help would be appreciated.
