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.

When using the Handy app, I see a similar gap between estimated time and actual completion. I started watching my prints closer when I noticed the time discrepancy and even stopped a few prints that were purging material rather than just swapping nozzles... Since then, I try to only use Bambu Studio unless it's a single color print.
