On a side note, this is a good time to mention that learning to simulate RFNoC blocks with the excellent and comprehensive testbench framework Jonathon put together is the single most effective way to write better RFNoC blocks, faster. This kind of error would be caught almost instantly in simulation, instead of waiting N minutes for Vivado to synthesize and implement it.
It is absolutely worth your time to start working with the testbench now, instead of deferring because your block almost works.
