Don't know how this happened but a cell i created in my table with a few lines of wrap around text repeats itself in another location in the table i.e. Cell 1, Cell 2, Cell 3, Cell 2. I can select and edit the first Cell 2 but can't do anything with the second one. Can't select it, edit it or delete it. What went wrong?

Check to see whether Repeat Header Rows is applied to the first instance of that cell. If it is, then only the first one can be edited, and the rest are repeated copies placed there by Word.
