Seems like you've used 1 coin in Goblin Prince and 2 in The Blind Rune.
I've checked it and it is a bug. We forgot to check the coin usage in the new game. Fixing and refunding you 2 coins to let you finish the quest!
Thanks for reporting the problem :)

Reported bug has been fixed and you've been rewarded with Rookie chest as a refund to finish your quest.
Check your rewards tab.
Greetings, @taverngames
