MPPT 150/60 is bulk charging higher than normal

Absorption voltage set to 14.7V and history shows max: 15.3V. Started about 26 days ago. Will this cause problems for my Trojan FLA batteries.

I guess it is the temperature compensation, this will rise the voltage at temperatures below 25°C. Look at your battery settings of the MPPT.
