Cant assign samples from sample pool

I just updated to 2.6 and after I updated I cant add samples from my sample pool and assign them to pads , if i load up 10 samples into the pool I used to be able to touch a sample then touch the pad I want it on and it would be there. Now it wont let me go this. Anyone know why ?

Its in the list of changes in 2.6 in the updated manual.
Double tap the pad now. Keeps people from accidentally assigning stuff when you fat finger the wrong pad.

Thank you !
