SigmoidLayer wont work while implementing on ZC706

layers = [
    imageInputLayer([800,1,1], 'Name', 'input','Normalization', 'none') % input layers (800, 1, 1)
    % encoder
    convolution2dLayer([3,1], 64, 'Padding', 'same', 'Stride', [1,1], 'Name', 'enc_conv1')
    reluLayer('Name', 'enc_relu1')
    convolution2dLayer([3,1], 32, 'Padding', 'same', 'Stride', [1,1], 'Name', 'enc_conv2')
    reluLayer('Name', 'enc_relu2')
    convolution2dLayer([3,1], 16, 'Padding', 'same', 'Stride', [1,1], 'Name', 'enc_conv3')
    reluLayer('Name', 'enc_relu3')
    convolution2dLayer([3,1], 4, 'Padding', 'same', 'Stride', [1,1], 'Name', 'enc_conv4')
    reluLayer('Name', 'enc_relu4')
    % decoder
    convolution2dLayer([3,1], 16, 'Padding', 'same', 'Stride', [1,1], 'Name', 'dec_conv1')
    reluLayer('Name', 'dec_relu1')
    convolution2dLayer([3,1], 32, 'Padding', 'same', 'Stride', [1,1], 'Name', 'dec_conv2')
    reluLayer('Name', 'dec_relu2')
    convolution2dLayer([3,1], 64, 'Padding', 'same', 'Stride', [1,1], 'Name', 'dec_conv3')
    reluLayer('Name', 'dec_relu3')
    convolution2dLayer([3,1], 1, 'Padding', 'same', 'Stride', [1,1], 'Name', 'dec_output')
    sigmoidLayer('Name', 'sigmoid_output')
    ];
hTarget = dlhdl.Target("Xilinx",Interface="Ethernet",IPAddress="192.168.1.101");
hdlsetuptoolpath('ToolName', 'Xilinx Vivado', 'ToolPath', 'E:\Xilinx\Vivado\2024.2\bin\vivado.bat');
hW = dlhdl.Workflow(Network=net,Bitstream='zc706_single',Target=hTarget);
dn = compile(hW);
deploy(hW);

while I deploy the sigmoidlayer the output from ZC706 fpga the output is zero after sigmoidlayer, and the middle layers output's parameters is correct, it seems that the sigmoidlayers have some problems.How can I fix or it is a bug?
