Did you ever find a solution to this issue? I am having a similar problem when I invoke a budget report on any particular month, but no issues for a running total...

For those how, like me, reach this page the "uninitialized value" error is because Monthy uses "Assets:Budget" while all transactions are Personal. The "cannot convert a balance..." is expected [1]
