There is no problem, it's a product specification.
Manual says,
Connect clock input of the LL8 to a clock signal from a sequencer or LFO and the sequencer will start running. If the sequencer does not receive a clock signal for a few seconds, it jumps back to the first step of the sequence and waits until the clock continues.

I need help with LL8. After reset (disconnect clock for some seconds and send clock again) it always skip first step in pattern (no trigger out). Is it normal for LL8?
