"Auto-hide the taskbar" does not work

[qwert99]

Dear Madams and Sirs,

I check "Auto-hide the taskbar", click on "Apply", and then appear a table -

A toolbar is already hidden on this side of your screen. You can have only one auto-hide toolbar per side.

Please help me, how to restore a function "Auto-hide the taskbar"?

Thanks in advance.
