Error while doing Random sampling with limit by data grouping in split activity

[RajeshBhat]

Hi,

There is a static list in Adobe campaign classic created along with segment name field. Need to create 10% control group for each of the segments from the list. 

Attached the structure of the list below. These are the steps followed. 

1. Read list activity to read the data from list

2. Split activity, changed the filtering setting to "Use the additional data only" in general tab

3. In the split subsets selected limit the selected records option then activate random sampling > By data grouping (as a %) > selected segment name > all data groupings by same data size > value: 10

4. Please see the error when I execute this workflow.

Hi, I was able to resolve this error. But I see that split is not dividing the numbers accurately. When I do the random 10% grouping by segment name for control group audience, the numbers across each of the segments are not 10%. Some of the segments are having ~25% audience coming out from this split. Is this a product bug in split activity?
