Problems in sorting Media library and Enhanced media library plugin

Hello!
I must say your theme is great but I’ve found two problems when I’m working with the media library (I found it was problem with the theme because I deactivated it and everything worked fine). The first problem is that I cannot order the media library by file. Clicking on “file” nothing happens and files continue ordered the newest, the first.
The second problem is that I’m using Enhanced media library plugin in order to make categories for my files. When I’m in list view, in the top of the page there is an option to filter by category, but it doesn’t work and it always show 0 result.
Do you know what can be affecting?
Thank you very much!
