Jhon, thanks for taking your time. Your suggestion shows how to rename a previously entered value and it works (maybe I’ll need it in the future). I think I made the mistake at the beginning of the project a few years ago by not providing the possibility of inserting multiple values for that type of field: I started with a text type field and I continued with that by inserting values separated by commas . I will continue to use it like this for this project. The conversion of the field type from text to select creates the inconvenience that I have exposed in the question and that I cannot solve by myself. Thanks again
