It's all but impossible to know what's going on without seeing your flow, but I'll make a stab in the dark. Are you cutting out a section of the image, denoising, then putting it back over the top? The denoise might be pulling some black pixels in from the edge. If that's what you've been doing, try reversing the order of operations: Denoise the entire image, then mask it, and Merge the result.
