Location Status Formula Only Working for First Row

I made a spreadsheet to update a location/site status when data is entered into specific cells. Column A is the location by Site ID, column H is the Assigned Tech, and Column I will be a yes or no entry once the work has been completed. I want the site status in L2 to update from "Not Started" to "In Progress" once a tech has been assigned and then "Done" once the done column has been marked. The formula I have seems to be working, but only for the first row. If I enter a Site ID into K2 that is any other row other than row 1, the status is "Not Started" even with data in the Assigned Tech and Done columns. Help please!
