Sending a packet once but receiving multiple times at receiver side (GNURadio, Zynq702+FMComms5)

Question

Hello there, 
 The problem I am facing is may be not solely depends on FMCOMMS5 but also on my grc flowgrpah in GNURadio. I am asking though. 
 I am sending a '.txt' file once with 100 sequence of 0,1s by using OFDM simulation grc examples in GNURadio and also using a pair of zynq702+FMCOMMS5 set as transceiver. The software simulation transmitted it only once. But when I am transmitting it with FMCOMMS5, it recieves muliple times at the reciever side. That means the '.txt' file continue to receive more than 100 sequence untill I stop simulation with transceiver. 
 If anybody can give me some explaination or suggestion for modification of Board configuration or Flowgraph would be grateful. Please use below pictures for my reference model. 
 Note: I havent done any modification for transmission on both board just connected HDMI plug once for signal visualization in the oscilloscope. 
 Thank you.

If you set "Cyclic" to false, do you receive one sequence as expected? Do you still see a part of the expected sequence missing if you connect one zynq702+FMCOMMS5 in RF loopback i.e., connect the transmit and receive ports? Does your simulation work as expected when you remove all hardware, create a single flowgraph by just connecting the OFDM transmitter block to Throttle and the rest of the receiver blocks, and run it? Do you get the expected sequence without loss?)
