RAF: Blacks and whites in Silver Efex does not work really

//wrote it in fuji forums, but POTN is my home, so....


I use Silver Efex a lot and with RAF files I unfortunately noticing, that Blacks and Whites sliders does not work with .RAF files [at least when importing from LR. That's a real pity, because I love that adjustment as it work quite differently from PS/LR and really does what I need :/

or is it just me....

The above is without amplify and the below one is with 100% amplify. The difference is very slight in the curtains and highlights in the left side. dang.

I have not experienced this problem, but I just ran a test to make sure. Sorry for the poor job attaching the images.
