I have a dataset of 200 cases and I’d like to add some new ones to the bottom. I clicked on the last case and selected “Add new case” and a new case was added, but it was ABOVE the last case, not below. So I decide to delete it. Didn’t work – the case is still there. I closed the file, re-opened it and then deleted the case – that worked. Tried the whole thing again with the same result. So I think that newly-added cases are not deletable until the document is closed and re-opened. I didn’t try adding data to the case – maybe that would have fixed the problem?
I tried to reproduce this problem with a variety of datasets and have been unable to. I wonder if there was something about your dataset that provokes the problem. If you were able to tell us a little more about the dataset or provide a sample, that would be helpful for resolving this issue.
