Please give the batch number which is the numbers/letters at the end of the batch in brackets. That way people can look at it and help you with your concern.
Dave Morris6 suggestion above is very good. If you want an answer that fits with the problem others need to know what you are working on.
If you have a batch that only has one image then you don't turn the page, you complete the batch and submitted then get a new batch. If the batch has a pre set number of entries and you have excess blank entries you will need to delete those blanks using the trash can icon at the top of the page.
If your batch has more than one image you just click on the next image.
If you would like to watch a video that explains some of these things you could try
hope this helps
