No, its not a bug, but when you use Multiply immediately (without 
doing some Overdub or FB reduction) after Record, you get a problem 
really.

Just imagine how the sound is kept in memory:
You have one cycle recorded and we keep coping that to another cycle, 
ready to register eventual changes. As long as you dont do anything 
more, we just alternate between those two copies.
Now you do Multiply, which copies one of those cycles (depends on 
when you press Multiply exactly) 4 times with your new overdubs. So 
you have 5 or 6 cycles in the memory now.
Now you want undo all overdubs. But we dont have 4 subsequent cycles 
without overdubs in the memory!

So the solution is:
Multiply by 1 (press Multiply twice in a row) at the beginning of the 4 
cycles
Then press Undo to get rid of the overdub on that cycle
