Thanks, guys, for your response.
Lee D: I have realised what I was doing wrong in the Preset selection. I was clicking on the down arrow next to the Preset box, whereas I need to click on the three lines just to the right of the Overlays box.

Problems solved, though I'm sure to be back as I am going to buy Affinity Photo. So much more powerful than Elements (which is too much biased towards guided edits) and so much more affordable than Photoshop. As a retired amateur I cannot justify the ongoing PS cost. I will miss the convenience of Elements Organiser, but can still use it with some effort.
