Single option drop down stores array??

[tghounsell]

I just created a dropdown field with four options and set multi-select to "off". It shows as expected, but it stores an array with two values in it. A user selects what should have a value of "3" and it stores ["3","0"]. Why? The second value seems to indicate the previous selection. Is there a way to have it store only the last selection?

If not, how should I use pre-filters to filter out selections based on only the first value in the saved array?

I can't replicate, it's storing only the value.
Did you set anything in "Frontend additions"?

I did not set anything in the frontend additions. I ended up replacing the element with a yes/no element. After reading your comment, I tried again and I also could not replicate it.
