Post [Q] Can't change the download directory to external SD card

Hi all, After upgrade to the Resurrection Remix Kitkat Rom v5.0.9, I found that some apps like Dolphin browser, Camera 360 can't set the download path to the external SD card , but K9 mail can be changed to ext. memory card just like previous JB. Can someone confirm that?

And one more question, I copied some of my favorite ring tones, notification sound to the proper folders under /system/media/audio/. But why they are always displayed twice in the phone ring tone / default notification sound selection panels? And how to get rid of them? Thanks a lot.
