As with many things unexpected, "that's strange" jumps to mind.
The most likely conclusion is there's a hole in the logic that creates the list of Scheduled Entries to commit vs. the logic that determines the Next Entry Date for each Schedule. The easiest way to troubleshoot that is for us to have the details of that particular Schedule. Can you send screenshots of its Debit & Schedule tabs so we can duplicate the issue here?
Here's how to create screenshots of a specific window:
1. Hold down the Apple key and the Shift key with one hand.
2. Press the 4 key above the letters on your keyboard. A crosshairs will appear in place of your mouse pointer.
3. Press the spacebar once. The crosshairs will change to a camera.
4. Move the camera over the window you would like to create a picture of. The window will become highlighted, indicating the screenshot will be of that window only.
5. Click your mouse button once. The camera will disappear, replaced by the regular mouse pointer.
6. Look on your Desktop. You will find a file named "Picture XX", where the "XX" is a number from 1 to the number of screenshots currently on your Desktop. If you've never done this before it should be named "Picture 1".
Please use these instructions to take a picture of the Debit & Schedule tabs for the Schedule in question and send the results to
support@splasm.com. We'll use the same settings to set up a Schedule here, duplicate the issue and let you know our findings. Thanks!
