I choose to see a Pantone colour as CMYK sliders and the spectrum box became huge. At the same time, the swatch panel misbehave, and I couldn't add any colour/gradient to it.

I am running Affinity Photo 1.6.1.93 on Win 7 Pro 64 bit. A photo scan with prominent paper texture stipples - circular bumps - throughout in regular arrays, failed to generate an FFT spectrum after running FFT Denoise. Procedure: I tried full photo, then later a smaller all white area. I selected FFT Denoise > Spectrum panel > Apply > FFT Denoise appeared to run > result: nothing, all black, no FFT spectrum generated. What am I doing wrong?
