Sort by numerical values in the Filter in Map Viewer

[RyanBohan]

When configuring a filter please sort by integer (numerical) values in the same way the attribute table is sorted.

Currently after sorting A to Z

The values are not sorted in numerical order (CPCODE is an integer) It goes 18, 19 ,2 ,20 ,21, why is 2 between 19 and 20?

Please sort in the same way the attribute table is sorted 1,2,3,4,5,etc

Thank you.
