Tempo display

[rob-ant]

Hello. The tempo on my ndlr has begun showing 480 BPM yet is hooked up to my DAW set at 120 BPM. I've just noticed if I slow DAW down to 20 ndlr shows 80 so 4x20. 480 = 4x 120. It's not playing at 480 BPM. Any thoughts as to what might be occurring? It's set to clock in USB1 and 'tic' in red is flashing rapidly. Don't know what tic means. 

Thanks

Rob
