Show us screenshots of the result and your clone brush settings as well as your timeline.
I'm having the same problem. But if I open the photo directly in Photoshop from my desktop (vs. opening Photoshop when my photo is in Lightroom), the clone tool works.
I'm also having the same problem and I'm sending a screen to see if someone can help us. The red "crosshairs" in the yellow rectangle are the ones mentioned by heatherm59177256. I've tried using the roto brush, but instead of copying the blood from the top, it only gives me those thin lines as the brush size was ridiculously small. My brush size it at 28px at the moment. Also paling opacity and flow at 100%.
Any help would be must appreciated.
Check your paint panel settings - particularly things like channels, mode...
Thank you for your suggestion. Actually I found out the problem was on the "Brushes" settings, under Brush Dynamics> Size. The default was set to pen pressure and once turned of, it gave the regular results of the Roto Brush tool.
I hope it helps the others too.
