What are the task bar jump lists line spacing registry keys or Classic Shell settings?

My task bar jump lists were single spaced but the lines have progressively become wider spaced ‘on their own’.

I’m not sure if this is a Classic shell setting or a windows one. I have classic shell start menu installed.

The left click list is wider spaced than the right-click list so there must be 2 keys/settings.

The actual Classic Shell Start Menu is how I want the lists to look.
