The problem is that the protocolType for the windows variant is never set before we go to editing https://github.com/aerogear/aerogear-unifiedpush-server/blob/6ad62a16bbbb9f838acc85c7c3511a0097c90b9f/admin-ui/app/scripts/services/variantModal.js#L70

Looks like it's set only when we create a variant, but this info is lost after reload.
Lukáš Fryč Could you take a look ?
