Hi! Any clues as to where to start to understand this odd budget report behaviour? Browsing the code, I wondered if I should start pulling the code apart here: https://github.com/Gnucash/gnucash/blob/master/gnucash/gnome/gnc-budget-view.c#L1011
to understand why the totals would be combined in such an apparently-illogical (but presumably profoundly reasonable to a better-informed person!) way... Hints very much appreciated!
