The amount of bDIGG tokens (share of the deposited DIGG) are correct, but it looks like the value calculation you are using is just taking that quantity and multiplying it by the current DIGG price which is incorrect.

You should be looking at the bDIGG's underlying DIGG quantity (given the rebases). Then multiplying that by the current DIGG price.

Here is a screenshot of what I am referring to on the BadgerDao dApp.

Thanks 🙏
