After buying 85 shares of Vivendi (bringing the total to 303 shares), Quicken Home & Business 2017 calculates an insane cost basis for the shares. If I remove the transaction, the cost basis seems to work fine. As soon as I add the transaction again, the insane cost basis returns.
Here's the transaction that I entered:

Here's the cost basis report of Vivendi before the transaction was entered:

And here's what it looks like after the transaction is entered (note the crazy cost basis):

I've tried running file validate/repair, but it neither reports that there's a problem nor solves it.
I've tried changing the number of shares bought, the price, and even the date purchased, and it still results in a crazy cost basis.
Any ideas?
