Hi @Pranay_Bisht

For datasets, as in images you have uploaded and annotated into Roboflow, you can update the label or exclude them from generated versions using the [Modify Classes](https://help.roboflow.com/guides/modifying-classes) augmentation.

For generated versions, as in where you already selected your pre-processing, augmentation, and generated a version of the dataset, those are “moment in time”. This means that once they are created, the individual versions don’t change, but you can always generate new versions under the Generate tab and click “Generate New Version”.

Thank you so much for taking out the time and replying to my query, although I had figured it out on my own later but still I really appreciate your response. Have a great day!
