I am trying to create formulas that skips weekends, showing 5 days after a date field called Sendt (and then two other formula fields for 14 days later and 30 days later)

I tried using the workday function, however it is displaying a Sunday, as you can see in the screen shot below.

I have tried, I kid you not, over 30 different types of formulas and cannot get this to work. 

What am I doing wrong and how I can get the formula to spit out the next BUSINESS DAY 5 days after the Sendt date?

For reference 3/27 is a Monday and 4/2 is a Sunday.
