Looking forward to help you,
I've tried with Ableton Live 8.2.5 (currently downloading 8.2.7),
Browsing the presets, I did not notice any sound problem.
Do you have element that could help reproducing systematically this problem ?
Or could you describe your context a little bit further ?
For your information, we are currently working on the Prophet-V 2.5 update that includes support for 64-bit hosts, improvement for MIDI assignment and many bug fixes. This update will be release during december.
