Hi @rashcl welcome back!
Right click on the DG minimap icon, or you can rightclick on the guide frames and then click the gear cog to enter Settings.
Click on Dugi Arrow and then untick Icon arrow. This should bring back the Classic Dugi Guides Arrow.
To move them, hold the CTRL key down then drag the Arrow / Zone Map to where every you like them to be.
To Lock them, same again, hold the CTRL key down, then right click and choose ‘Lock Arrow’ ‘Lock Zone Map’.
I hope this helps you
