And then I can see the blending in the preview. It looks like two adjacent image mixed. It's more obvious when set 'h' higher. When set 'd' to 0 the blending disappear.

Isn't it a normal behavior of NLM? The NLM filter equals simple average filter in both spatial and temporal domain as "h" approaches infinity, and setting "d" to 0 means spatial-only filtering, thus no temporal blending will occur.

It's not an issue as @WolframRhodium said.
