Just got an UOA back

I tested my oil(rotella T syn 5/40) @ 5k and @ 7.5k miles. I guess my engine doesnt like the syn or its cleaning out the engine. What do you think?

Iron:
15@5k
29@7.5k
17AVG

Lead:
8@5k
9@7.5k
4AVG

TBN @5k: 9
All other fields are below average
Blackstone says to drop back down to 4500mile interval and recheck. If lead is bad again, try a dino oil.

What should I do?
A: change NOW with the same oil, go to 4.5k and recheck
B: change NOW to regular rotella T, go to 4.5k and recheck
