A couple of recent transactions have mis-matched (I have since changed them to 'exact match' to try to minimize that).
But what I noticed: If I edited and updated a series, to backdate next occurence to original date, after hitting update the series would update but the projected cash flow would not update. IF I then edited the series a second time, didn't change anything, then hit update, the projected cash flow would update.
I don't have screenshots because i already fixed all instances of this happening.
