Sort order in Potentials incorrect

Sort order in Potentials incorrect

I deleted all of the stages in Potentials Stages and replaced them with new values. I was careful to enter each stage according to where it ranks (i.e., 1, 2, 3, 4...). When I sort by Ascending, the sort order is incorrect. It worked when I sorted by Descending but now it is frozen. I just started using Zoho today!
