Error CS1614 when importing Photon Voice

Hey,

I just updated my project to Unity 2017.1.0f3 and Photon to 1.85.
Tried to import the latest version of Photon Voice from the assetstore, 1.11.

After importing, I'm getting 2 errors:
1) Assets/PUNVoice/Scripts/PhotonVoiceRecorder.cs(11,2): error CS1614: 'HelpURL' is ambiguous between 'HelpURL' and 'HelpURLAttribute'. Use either ' @HelpURL' or 'HelpURLAttribute'
2) Assets/PUNVoice/Scripts/PhotonVoiceRecorder.cs(9,2): error CS1614: 'HelpURL' is ambiguous between 'HelpURL' and 'HelpURLAttribute'. Use either ' @HelpURL' or 'HelpURLAttribute'

Cheers,
Frosty
