How to properly set up axis_broadcaster with concatenation "remap string".

I using axis_broadcaster to construct concatenated bus like this:

M00_AXIS_TDATA : Remap string set to : "8'b0,tdata[63:56],8'b0,tdata[55:48],8'b0,tdata[47:40],8'b0,tdata[39:32],8'b0,tdata[31:24],8'b0,tdata[23:16],8'b0,tdata[15:8],8'b0,tdata[7:0]"

and 

M01_AXIS_TDATA : Remap string set to : "8'b0,tdata[127:120],8'b0,tdata[119:112],8'b0,tdata[111:104],8'b0,tdata[103:96],8'b0,tdata[95:88],8'b0,tdata[87:80],8'b0,tdata[79:72],8'b0,tdata[71:64]"

Everything set like written in : "PG085 December 5, 2018" page 36.

 

But in my verilog wrapper not get  what I rely want to get...

I get a wrong right-aligned bus:

wrapper.v:

 

...

wire [127:0]axis_broadcaster_0_M00_AXIS_TDATA;

...

wire [255:128]axis_broadcaster_0_M01_AXIS_TDATA;

What am I doing wrong?

Thank.
