Spacing slider is not working in pattern fill

[r3amd5099603]

All other adjustment sliders in pattern fill are working pretty normal but spacing slider. It stopped all of a sudden. Please help me out.

Hi there,

Sorry to hear about this, could you please let us know the version of Photoshop and operating system you're working on?

Also, what pattern are you trying to apply?
Does it happen with only one document or every document?
Have you tried updating the Graphics processor from manufacturer's website and see if that helps?

Regards,
Sahil

Thank you for your reply,

I am using Photoshop 2015 CC. It happens with all the documents. The spacing slider is grayed out.
