@javcin perhaps it would help if you explain what you are trying to achieve with your workflow.
If following a PS tutorial on blemish removal you need to consider that AP and PS operate differently. In AP any adjustment or filter layer effects any underlying pixel layer, so with paint brush tool colour sampling, you are effectively sampling a 'black and white' image, hence no colour is picked.
If using frequency separation and or curves adjustment to highlight blemishes you may find the use of inpainting brush or other blemish removal tools useful.
