P6 resource leveling pushes activity to individual day

I'm using P6 for scheduling a project.  

I have 3 activities that don't seem to level correctly.  See below for example.

• All are Task dependent activities
• Same resource assigned to all activities
• Calendar is set to 8 hours/day work schedule

I have 3 tasks with no logic between them, but they all use the same resource.

• Task 1 - duration equals 7 hours
• Task 2 - duration equals 2 hours
• Task 3 - duration equals 7 hours

When resource leveling is performed, Task 2 pushes to a separte day and Task 3 goes to a third day. Results below:

• Task 1 starts on Monday
• Task 2 starts on Tuesday
• Task 3 starts on Wednesday

I want and expected the following results (all work completing in the 16 hours of Monday and Tuesday):

• Task 1 starts and completes on Monday
• Task 2 starts on Monday and completes on Tuesday
• Task 3 starts on Tuesday and completes on Tuesday

Any help is appreciated.

Update: I was just informed that the individual was using days for activity duration versus hours while trying to use hours available for resources.  I believe this is where the error is occurring and why the result is not as expected.
