Imported texture not showing up on model

hi, I'm attempting to make some recolours of some cc skin and eyes however when I import the texture in s4studio it doesn't change the model.




As you can se the texture on the right is different to the skin colour on the model, This happens with everything I try to recolour. This happened a few weeks ago but sorted itself out after a week or so but its doing it again and not fixing itself, I tried uninstalling and reinstalling s4studio but it hasn't worked. 

Also something similar is happening when I try to edit a recolour of some eyes I did ages ago. 

In game the eyes look like this -



But when I open the CC in studio they look like this - 


Which are the original eyes that I recoloured in the first place, I need the texture of the eyes shown in game but when I export the texture it's of the eyes in the studio. Please help this has been happening for ages
