In Setup, under Rules, if you double-click on whatever is listed under "Salary Rules," you will see a window like the one below:
(If you don't see anything under Salary Rules, you will have to create one.)
All of the hour types checked are included in the salary deduction. If you want to reserve an hour type to adjust salary hour amounts, create an hour type called something like "Manual Salary Adjustment" in Hours/Monetary Types, then remove its check mark under Salary Rule.

(Hours/Monetary Type)
Last, please doublecheck that the employee is assigned to the Salary rule by going to Employees >> [employee] >> Employment.
Then, whatever amount you enter on the employee's timecard using "Manual Salary Adjustment" (or whatever you call the hours) will not be included in the salary adjustment, so if you enter positive numbers, they will be added to the employee's salary hours for that pay period. If you enter negative numbers (e.g., -8 for each day they were not present), that total will be deducted from the salary hours.
