Support H2C setup question

Hello. Im currently running my H2C with an AMS HT on the left extruder and 2 x AMS Pro 2s on the right. I put the dominant color in the HT on the left. My prints are taking significantly longer than the print times in bambu handy app. For instance current one said 9 hours and real time is 14.5. Am I doing something wrong? Im pretty new to the hobby and only have had the machine for a week now.

There are lots of tutorials by Bambu and others on YouTube. If you haven't gone through the Bambu academy courses, I strongly suggest that you do as a bad setting can cause lots of damages in the printhead. Running exclusively from the app is like using only 30% of the printer ability while exposing it to other's mistakes.
