Rename Layers wrong order
When I go to rename layers, and use the `{{n}}` which means Ascending (1, 2, 3, ...), it will do it, but the layers are sorted in the wrong order. It's almost as if it takes the bottom layer of the selection, and goes upwards instead of downwards.

For example, starting with three blank Artboards,

If I rename them `Activity {{n}}` instead of "Activity 1, Activity 2, Activity 3" I get:

If I try `Activity {{N}}`, it seems to fix it... until I need to start at a later number, e.g. 6. If I try `Activity {{N6}}` instead of "Activity 6, Activity 7, ..." I get:

Hopefully that makes sense.
