FSBUS display problem

[fmw]

Hello

I have made the display board, with 2 boards and 2 3 segments board.

Now i have the problem, that the number 1,4,5 and 6 is not schowing correct. By number 1 the a and c bar is on, by number 4 the a,f,g and c is on, by number 5 the f, g, b, c and d is on, by number 6 the f, g, b, e, d, and c is on.
The rest of the numbers is correct. And the same problem on both boards.
The problem is on all segments.

Have any have the same problem?
