Podbird does not play sound reports 0 length in player view (correct time shows in recent listing)

Some podcasts do not respond when clicked, those that do have the pause icon but do not play, I can pause and play but nothing is heard.
Clicking on the play bar at the bottom of the screen opens the player screen which has a start and stop time of 0 seconds.
A redownload ofa podcast and restart podcastgets the podcast to play but looks like all podcasts need to be downloaded again making my library rather small now.

might not have worked since i updated to v48 of Ubuntu phone, music app plays correctly.
