[Discuss-gnuradio] tx_ofdm.grc & rx_ofdm.grc output data

Has anyone  tested successfully these two files combined?

The input data or vector source is an array of 96 elements [0-95] but I'm
getting a strange output at the end.

The 96 + 4 elements from the crc, then another 100 values (200 total), then
the sequence repeats.

I tried using the OFDM transmitter and receiver blocks and they work
perfectly, same input as ouput.

I began tracing the problem comparing the same log debug output files and it
seems the "Header/Payload Demux" is causing some issues.

Here's the output at the very end of the RX by the way (200 elements, then
repeats):
