Photoshop spot healing brush leaving black spots

[#1]

Hi! 
I have a strange problem. 
my spot healing brush are leaving black stains. (Se photos) 

 

also I have a simulator problem with my clone stamp where when I can pick up the clone but after I tries to add the clone over my tripod here, it takes a few seconds and a big black mark is added. 

does anyone have similar problems or know how to fix this issues. 
I am a beginner at Photoshop.

Without seeming your full screen, it's hard to say, but it looks like you might have an adjustment layer above the layer that you are retouching, and it is adding that extra correction to your retouching. Make you you have the tools set for current layer only, or turn off any adjustment layer.

I am having the same problem. Every area I try to heal just leaves black as if I were painting. Have gone from 16 bit to 8 bit, worked in both RGB and Grayscale. Same result.

Same. Only way to get rid of it is to zoom in or out.

Hi.. I'm having the same issue. I get the black painting where I'm spot healing. It only goes away when I zoom in or out. I have tried resetting the tool. It keeps happening.

Problem is fixed!!!  I reset the preferences.

EDIT-->  PREFERENCES -->  GENERAL -->  Check off  RESET PREFERENCES ON QUIT. Close Photoshop then start it back up. Preblem resolved.
