Issue with IQBot Extraction 360 (Preview) Validation Files

Hello Expert,

Im a newbie and currently doing Bot Games: Invoice Processing - Accounts Payable

1 of the steps is to extracted the data from tiff files, im using IQBot Extraction 360  (Preview) as im unable to use IQ Bot (local device) or IQ Bot Extraction in task bot. But out of 7 files, only 3 is success while the other 4 is places in validation folder. My question is how do I proceed with the validation files, i checked and the csv is extracting the data fine. I try to process back the 4 files using the control panel learning instances, but the files is process fine and no validation required.
