Min Support on FP-Growth

Hi, I'm new to RapidMiner.
Currently I'm practicing about association rule.
I set the min support for FP-Growth 0.5 (50%), but the support value on results below what I've set
Here a screenshoot some of the results


I thought the results of support value should be above the given min support
Can anyone tell me what's going on here?
Thank you

    If you check the option to find the "min number of itemsets" then this will take precedence of the cutoff on support. If you want to get only the itemsets with the minimum support required then switch the option off. Jacob
