The extra spaces in your existing formula in M6 wont allow the other dependent formula to give correct results. For instance you have "OOP vs 1 opponent " with an extra space at the end whereas in the formula in column O refers to just M6 being just "OOP vs 1 opponent".

Also your existing formula starst with " "&choose(.... whereas your dependent formula dont have those spaces.

Try the formula in my above post and let me know if you get desired results
