Filter Example Range and a Potencial Problem Detected

I asked a question a few days ago about how to get the top5 of clients according to the criteria that they will choose, to which I got as an answer to use the Sort operator and then Filter Example Range. It worked, since it throws me the values in a table with the 5 best ones, as you told me in your comment, because I used the Sort operator. Then use "Filter example range" with the first example = 1 and the last example = 5 to get only the first 5 following your instructions. However, it tells me that there is a "potential problem detected: the first_example parameter indexes an example, but the value 1 exceeds the size of the set of examples". What do you mean by that mistake? How can I solve it?
So do you have any screenshot of the error and your data?
RapidMiner sometimes can't determine the future number of records coming from an input operator.
If you ever read a shorter CSV file, for example, then the Filter Example Range operator will fail because it expects 5 or more examples.
In your case, the process works, so this is just an information to you about potential future problems.
