Post your code, using code tags please. Instructions are in the forum guide. If the code is too long to post, please make a short sketch that illustrates the problem.

But your diagram only shows the Arduino wired to one display. Are the two displays being chained or is the connection to both displays common?

So according to the guide lines in How to use this forum which you no doubt will have read before making a post here, then you should supply links to obscure libraries.
