How does Israel undercount its cluster bombs? It does not count them as bomblets although each are separate bombs after they are released

"The New York Times Correction: August 30, 2014 

An article on Thursday about a report on the deaths and injuries caused by cluster bombs in the Syrian civil war overstated the number of cluster bombs Israel dropped on Lebanon during the conflict with Hezbollah in 2006. It was about 1,800 bombs, containing more than 1.2 million bomblets; it was not “hundreds of thousands” of cluster bombs."
