You probably selected the "Calculate F4" recalculation option when you should not have.  If you enter data for Format 4,  The "Calculate F4" recalculation option should NOT be selected. This selection tells Empower to take the time-phased EQP data and calculate the Format 4 data. If you don't have time-phased EQP loaded and select "Calculate F4" it will end up zeroing out what you loaded/entered.
