Amount on conversions on Ad Group view doesn't correspond with sum of conversions from keywords view

I have few keywords that have conversions. When I summarize all those conversions my result is much lower than a summary of conversions from Ad Group view.


Why? It's like 5 vs 18.

It seems to me that if you have Broad Search and Search Match options enabled your ads are shown the keywords not listed in the report so you don't see any conversions for them.
