Your CheckBook balance should update immediately after an Entry is removed for both the Running Balance in the Balance column and interactive Balance at the bottom. First, verify that your Entries are sorted by Date since this is the only situation wherein the Running Balance will show the actual account Balance at either the top or bottom of your list of Entries. To sort by date, click on the Date column header. To flip flop from ascending to descending chronological order or vice versa, click again.
If that doesn't help, perhaps you could send us a screenshot of your Entry section to
support@splasm.com and we'll see if we can spot some discrepancy. To take a screenshot, hold down the Command and Shift keys on the keyboard with one hand and hit the number 3 key with the other. You'll hear a camera shutter sound and an image file will save to the Desktop. Attach that image file to the email.
Thanks!
