photoshop perations / actions with cached CSV files

hello everyone, I have a problem with Photoshop, and more specifically with variables ... I am explaining what is going on step by step:
step 1. I have prepared a CSV file with variables for photoshop (15 records)
step 2. I record an operation that opens the project, loads the file with variables and, on its basis, exports PSD files to the selected directory (15 separate files)
step 3 stops recording the action - I check the action is working properly
And up to this point, everything is fine.
step 4.open the previously prepared CSV file with variables, delete 5 records from it (10 remain) and save the file with the unchanged name
step 5. I run the previously recorded operation and photoshop instead of 10 PSD files throws me 15 PSD files as it was originally in the CSV file with variables ----- WHY IS IT like that?
Does photoshop load the CSV file with variables somewhere in the cache and use it all the time until you manually point it to the new file?
Does photoshop not load a CSV file with variables every time it runs an actio
