Subtracting Calculated Columns from Each Other

[Niiru1]

I have absence data:

ID	Start	End	Duration	Days in Month	Working Days	Leave Entitlements	Days Available	Absence	Net
727	02/01/2019	07/01/2019	6	31	23	2.5	20.5	6	14.5
727	10/03/2020	11/03/2020	2	31	22	2.5	19.5	2	17.5
1150	03/06/2019	07/08/2019	66	30	20	2.5	17.5	7	-48.5
1150	03/06/2019	07/08/2019	66	30	20	2.5	17.5	31	-48.5
1150	03/06/2019	07/08/2019	66	30	20	2.5	17.5	28	-48.5

Where I'm subtracting [END] - [START] = Duration and then subtracting the ABSENCE from this.

However for periods longer than 1 month it groups the total (66 days) rather than individual days (7,31,28) is there a way to get it so the chart is like:

ID	Start	End	Duration	Days in Month	Working Days	Leave Entitlements	Days Available	Absence	Net
727	02/01/2019	07/01/2019	6	31	23	2.5	20.5	6	14.5
727	10/03/2020	11/03/2020	2	31	22	2.5	19.5	2	17.5
1150	03/06/2019	07/08/2019	66	30	20	2.5	17.5	7	10.5
1150	03/06/2019	07/08/2019	66	30	20	2.5	17.5	31	-13.5
1150	03/06/2019	07/08/2019	66	30	20	2.5	17.5	28	-10.5
