[Discuss-gnuradio] Data loss during transmission (OFDM .bmp file)

Hello All,
We are trying to transmit a .bmp file using USRP Tx/Rx. However, I am getting bogus header data at the receiving end. I tried transmitting a text file also which clips my starting text and also it inserts some invalid/unknown characters. We are losing some of the bytes for e.g, the transmitted file size is of 426316 bytes, but receiving file size is of 4,264,224 bytes.
Can somebody explain what we are doing wrong here. I have attached my Tx and Rx .grc and snapshots for the reference.
