Magnetic Selection Tool and chromatic aberration

Magnetic Selection Tool / chromatic aberration

I have 2 problems: 

1- Magnetic Selection Tool works the same as the Freehand Tool. It’s nothing like the video on Affinity.

2- Affinity does not get all of the chromatic aberration out. Photoshop gets it out simply and completely, but no matter what I’ve adjusted Affinity only partially removes it.

Is there anything I should know about these 2 issues.

I use Affinity on an iMac 10.14.6.

Thanks

1- I haven't seen the video but it works for me

In fact the Help is pretty good too

• With the Magnetic type:
  • Single-click then drag to add magnetic nodes that snap to edges.
  • Click-drag to add freehand lines to the selection.
  • Hold the   whilst single clicking to add straight lines to the selection.

Thanks for your help. I use a trackball so that may be fouling it up. I'll have to fool around with it.
