Calculate Days Between Tasks in a Project

I am trying to calculate how many days there are between the completion of one task and the start of another. Each project has tasks ranging in number from 1 to 14. I'm working with multiple projects...

Please clarify your needed logic, as you have some that are out of order. For example, for Project A, Task 7 starts before Task 6 ends.

Here is some cleaned up data with corrected dates. I'm trying to figure out how many days pass between the end of one task and the start of the subsequent task for each project. I found DAX to calculate the total project time on a different community page. I tried adding another variable for the Task Name so it would calculate the days between each tasks for individual projects but it returned blanks (see below).  I'm new to Power BI so I may be missing something.
