Fluctuating numbers in Filter tool

[Alteryxuserhere]

Hi everyone 

I have a very frustrating issue where every time I run the flow the numbers in the  filter tool changes when I have made no changes to the workflow. I have tried changing the input file to be a static file where numbers do not change but for some reason, the numbers still keep jumping around every time I run the flow. 

Does anyone have any idea what the issue could be?

@Alteryxuserhere ,

Can you show us the sample input data and the expression in Formula Tool?

Unless you are using the Random Sampling tool, the data stream should stay same for each run.

Can you share the workflow with sample input data we can take a closer look?
