Hi,
I have no issues with either VST2 or VST3 in my DAW.
So if you have issues with all Prophet VS presets, then it look loke it's DAW specific or you have something going on, that cause this issue.
Arturias VST2 and VST3 use the same ID. I can't have both versions availble in my DAW at the same time. If i remove the VST3 version or shut down my DAWs VST3 support, then i can use the VST2 version. You can test your VST2 version, and see if the issue is with the VST3 version only.
As long as i don't have Ableton Live, then i can't test and help further.
You can ask Arturia support, if they have this issue in Ableton Live.
