Pencil Texture reverts when color is chosen

Hi there,
I am unable to change the color of a line without it reverting back to normal line.

Process:
I draw a textured line
I then choose a color to use on a different line -
Its reverts all the line I have drawn till now to clean lines.

I have attached a video showing whats the problem

Please help if possible.
thanks
