[minor bug] Delete file selection

I'm using Podkicker Pro v1.5.4
Phone:  Samsung Galaxy S2 with Android 4.04 (stock, non-rooted) and it's on Sprint (SPH-D710)

When I click on the trash can in the downloads section to delete files, I noticed the following behavior.

Tap Select Listened >> Selects only listened to files
Tap select all >> Selects all files
Tap Select Listened >> Remains with all files selected.

Same issue with "select old"

Once you hit "select all", hitting the other keys to change your selection (if you mis-fingered) doesn't work; the buttons are visible but not active.  The delete and cancel buttons are the only two remaining buttons that work.

Please make the select buttons work all the time, or gray them out when they are not truly an option so I know to cancel, and then press more carefully the second time.
