Colour overlay not working!
So i'm a clothing designer that uses photoshop to construct prints for garment's, since starting in a new company and using there Photoshop CC i have come across this problem quite a few time's and its very very frustrating, when ever i double click my layer to change it to black (because that how i set up my screen's) it won't actually change! I was wondering if this was some sort of bug that other people are experiencing and if there is a way to fix it, i have tried looking through the preferences and comparing it to my computer i use at home but there is no difference to my home set up! Any info on this would be amazing.
(This has now changed to only one layer seems to have to problem, this white layer that is shown is the only layer that wont colour overlay!)
