Hi Tenno, we have seen some players on all platforms a bit confused by this over the year. 

First, have you checked your Inbox Messages in game? Go to Options > Communication > Inbox. The Message should be titled "We will use this to our advantage"

Another point of confusion: the Mods preview shows a fully upgraded version of Molten Impact. However, you are receiving a base Molten Impact that requires modding. When Mods are shown, they are previewed in their upgraded forms, so that the player can see their full potential

Hope this helps clarify!
