Layer problem with Assistant and layer selection

[CedarHouse]

Using Windows 10 and Affinity Photo version 2.5.7. Edited my image and then highlighted all the adjustment layers and assigned to a Group. Wanted to to a Soft Proof for printing etc. Selected Soft Proof from Adjustment layers and placed the Soft Proof layer above the Group Layer. Used Assistance to select insert layer based on Selection. Highlighted the Soft Proof layer and wanted to insert the layer Curves into the soft proof layer but it inserted above the Soft Proof Layer. Moved down the Curves layer in to the Soft Proof Layer manually. But the Curves layer did not act with the Soft Proof Layer. Tried with the HSL layer same happened and this layer inserted itself above the Soft Proof Layer even though the Assistant was set to (by selection). Moved the HSL layer into the Soft proof and again the HSL layer did not change anything in the Soft Proof layer. The grey areas in the Soft Proof did not change using Absolute Calometric when trying to adjust with either Curves or HSL.I was following exactly the process discussed by Robin Whalley in one of his You Tube videos titled Using the Soft Proof Tools in Affinity Photo.

Sorry for above, got my layers in the wrong order for soft proofing to work. Had a break and came back after a while and immediately spotted my error in the selection and layer choices. Needed the Soft Proofing later above my HSL Layer and Curves Layer and the Group layer below the two adjustment layers for it to work okay.
