Info: Numbers Sorting Bug Remains in Version 10.2
Numbers 10.2 did not fix the problem with sorting of tables that have formulas such as =COUNTIF(A$2:A4,A4) in a column. We use that kind of formula a lot here and this bug makes those tables unsortable. Table 1 in the screenshot is the original table. The "x" in "Ax" in the headers refers to a row number, like in the formula above. When sorted by column A in Table 1-1, the A$2 part of the range reference gets mangled, same as before. The lower rows came out correct but rows 2 and 3 are wrong.
