I have 2 monitors, and I want to keep my full taskbar persistently-visible on both of them. This was working fine until about a week ago. Now, it behaves as though "Main taskbar and taskbar where window is open" is selected even though "All taskbars" is still selected, until I toggle the setting myself.
My workaround is manually setting it to "Main taskbar and taskbar where window is open," then back to "All taskbars." This fixes the issue until the next time my PC sleeps.
I have tried resetting my PC and I have tried SFC /scannow as an admin in case of settings file corruption. Neither have resolved the issue.

I found the registry key to this setting, but changing it doesn’t solve the problem.
path: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced
set MMTaskbarMode to
0: All taskbars
1: Main taskbar and taskbar where window is open
2: Taskbar where window is open
Even when set to 0, It’s like the explorer doesn’t know that it needs to show the window icon on all taskbars on first time load.
Just adding a +1. RTX 3090 on latest official drivers with two active displays on Windows 10 latest updates. If the displays goes into sleep, when you wake the displays, the Always display all icons on both taskbars setting needs to be reset. Turning it on/off fixes it. Pretty annoying. I also think it started happening recently but not 100% sure as I recently discovered the option.
I'm having this same issue and I'm just wondering if you've found a permanent fix yet.
Thanks.
I'm having the same issue as well. It's driving me crazy as I often use those buttons on secondary monitor and I keep thinking the app must be closed.
It started from an update around last month or so.

Hey Kyo,
I have never messed with my startup or power settings, so I don't think that is the cause. I can test booting up in safe mode to see if it reproduces the bug or not.
My best guess is that this is being caused by a recent update. I ruled out file corruption because SFC /scannow did not resolve the issue, leading me to believe it was some sort of update from MSFT that caused it (BIOS, firmware, etc). I did not note a specific update or point in time where the issue began, though it was sometime in the last 3-4 weeks.
