Hi 2016,
Thank you so much for your detailed post and welcome to the Community Forum! I'm sorry to hear that you are having issues about your payroll. I really appreciate your patience and understanding about this issue, and I do apologize for the delayed response. May I ask whether you have enabled the "automatically adjust base hourly" option for your pay items? What I recommend is to visit this help article that will give you more information about: Setting up pay items
Feel free to post again, we're happy to help.
Regards,
Earl
