Modify Array formula - Reduce Calculation Time

Experts,

I have an excel file that has 2 array formulas.
It works but after I make a change to the file, I get a "calculating" in the bottom right and it takes too much time to calculate.

I am looking for a way to modify the array formulas or to do away with them and replace with something else (maybe IF statements).  

I thought that the calculation time was being caused by the data set being in table format and the Used Range being greater than the table data set but I converted to Normal Range and removed the surplus rows and columns to no avail.

Grateful for your assistance.
