In the My Homebrew Collection area, both "Name" and "Views" are able to be normally sorted in order and reverse order, but the other two do not.
Type:
By clicking on "Type", the page reloads and "/my-collection?sort=friendly-type" and "/my-collection?sort=-friendly-type" appear in the subdirectory of the URL. So it is reloading the page and trying to sort by the type, however it only ever shows alphabetical order for both regular and reversed Type sorting.
Date Modified:
Similarly, by clicking on "Date Modified", the page reloads with "/my-collection?sort=date-modified" and "/my-collection?sort=-date-modified" in the subdirectory of the URL. Yet again, for both normal and reversed sorting for "Date Modified" it only shows a normal alphabetical order.

I can confirm this. (It works fine under Creations, but not Collection.)
