Copie Past from paint.net to Realworld Cursor Editor

Hello there 😊

When I copie past something from paint.net to RW cursor editor, I get strange transparent white where it's empty.

When I copie past from RW cursor editor to paint.net, empty space are ok but the cursor is like 5% to the left and the other part is to the right.

Do you know how to configure paint.net or RW cursor editor to make copie paste without artifacs? Maybe another program works or how do I convert .png to .cur with RW cursor editor? My format is 32x32 smooth edge .

Thanks for the help 😊

Edit: Found the solution. Simply save as animated png in RW cursor editor.
