MCB(axi_s6_ddrx) in EDK is only working in burst mode of 4

I am using MCB in EDK and I am making some modifications to it. But I have found out the following results.

 

My write and read are working in burst of 4. Where can I change it?

For those who have worked on AXI interface, the MCB uses the write channel and read channel for making handshake between valid and ready signals. I am trying to delay each dataword I write and read by some clock cycles and I am delaying it in the read and write channels.

But MCB shows that for burst mode(4) data passes from the write channel. But for less than that it sometimes passes through write channel and sometimes not. What is the reason behind it. Say I am not working in burst mode. My data does not pass through the write channel but then where does is pass from. Basically I want to know the flow of data between channels for various burst modes.
