How can I move data from one field to another, then make the original field blank?

Question

I created a custom object that allows managers to input PTO marking the employee as out and unavailable for calls. Now they are requesting for 2 more PTO date options, with the data moving to new fields and making the previous one blank. I have been able to make the data transfer from PTO 1 to PTO 2, but it doesn't clear PTO 2, just duplicates the data. Is this a possibility at all? Here's the flow I used to attempt this. Any suggestions would be appreciated!

Assignments are not moves, they are copies. All you need to do is to assign the $Global.NullValue variable to the field you wish to clear out.
