The monthly cost is re-populating with unknown values and wipes out what was entered by the user.
When the 'Totals' column is positioned to the right of the Per-Period cells in a grid and the user is using the Tab key to do the data entry, the cursor lands in the 'Totals' column giving a total amount computed from the cells. The issue is that if the user updates the last period cell and then tabs to the Totals column the computed amount is not including the adjusted amount from the last period. Because the user tabbed into the 'Totals' field, it goes into a data entry mode. The 'Totals' amount should not be recomputed and 'spread' across the periods unexpectedly. The computed amount (less the last period amount) is then saved when the user tabs off of the totals field or clicks the 'Enter' key.
Steps To Reproduce:
(note: 300 + 300 = 600 total sum of periods amount)
Expected Results: The 'Totals' amount should compute to 600 and should NOT spread across the 2 periods.
Nov 2022: Cost=300
DEC 2022: Cost=300
Total Cost=600
Actual Results: The 'Totals' (sum of periods) amount is 300 ; it is missing the 300 amount from the last period and spreading it across the 2 periods.
Nov 2022: Cost=148
DEC 2022: Cost=152
Total Cost=300
