Cursor control mouse/trackpad dual monitors

I have an IMac Pro with Pro Display XDR as second monitor. It is configured so that the ProDisplay is the "Main" monitor and the IMac is the second monitor. The IMac is on the right and the Pro Display is on the left. When moving from right to left, if the cursor is in the upper 2" portion of the IMac dispaly the cursor will not move the the left monitor. I must drag the cursor down about 2" to get it to move to the left monitor. This behavior is constant in both a Logitech MX Master 3 for Mac mouse and the Apple track pad. Any way to overcome this "roadblock" in the upper left cornet of the IMac monitor?
