I am a fellowship applicant and received the same email. I responded explaining that I still did not have budget details for the summer program (African Languages Initiative) and was told not to worry about it - those numbers would be figured on their end and did not need to be estimated and submitted.
I applied for a Boren Fellowship this year, as well. Specifically the Swahili program of the African Languages Initiative in Tanzania. For the others who have applied for Tanzania, do you already have some knowledge of Swahili?
Two weeks and counting....good luck all!
