Broken attribute table for gmfs with multiples GMPEs and multiple IMTs

[CatalinaYepes]

For a scenario hazard calculation with multiple GMPEs and multiple IMTs the attribute table is displaying extra columns with NaN values, and some IMTs are skipped.

For example, a calculation with 3 IMTs = [PGA, SA(0.3), SA(1.0)] is shown as below.
Notice that there is not column for SA(0.3) and there are multiple columns for PGA.
