Spreadsheet duplicated within the same tab
My Numbers has about ten tabs. The main one was duplicated within the same sheet a few weeks ago, and I'm unable to correct it. In other words, I have a duplicate hidden behind the main sheet. This causes multiple problems. 1. One sheet is not updated. 2. When I do a search (CTL F), I get double the amount of entries. It makes the search challenging to find specific data. 3. I can't go above line 69. I tried to delete one, but then the calculations on the other one are then cancelled. I have attached a print screen. Thank you in advance for your comments.
