If package source list is empty, cannot add package source via UI (NuGet 3.4.x) (original) (raw)

When trying to add Package Sources, access the config via Options -> Package Sources. Enter a 'Name' and 'Source' (valid details to try and install Moq), but then when I select 'Add' the item is added as 'Package source' with a URL of 'http://packagesource' and the fields updated to be those same values.

Apologies, I'm not sure of the version (unsure how to find that) - however I'm running VS 2015 Enterprise 14.0.25123.
