Why is matrix size changing after demux in simulink?

I have a < 5 x 35041 double> matrix into a demux in matlab (a years worth of data sampled every 15mins/900seconds). From the demux the output that comes out is only < 1716x2 > (I checked this by attaching the scope to the output of the demux and saving it to workspace...I don't understand why the length is 1716.

Does anyone have any thoughts as to why the matrix is being truncated in length?

Use a Selector, this will give you a better control over the dimensions.
