I'm stumped on why my workflow is not giving me the desired output. I have multiple inventories from random days. I want the output to be a master inventory list with only unique items and the a count of when each unique item was in-stock. I cut back on the files feeding the workflow due to upload limits here, but when you run the attached it begins to show what happens to the dates that fall further away from the first date column. The number of occurrences are calculating less and less. For example, on this workflow "2022_06_03" should have 641 occurrences but the result is only 288.
Here is what the full output looks like and where the counts are off:
