I dont understand how acceleration can stay the same surely increasing the mass would increase the weight which would have a component down the slope increasing the force and hence the acceleration??

F = ma = mgsin(theta)
a = gsin(theta) (independent of m)

The component of weight down the slope increases but so does the mass. Hence a = F/m is unchanged
