You need to contact your HR because we can only answer generally without seeing the plan documents.
There are really two possibilities:
1. Your plan matches each payroll and ONLY considers that payroll in the calculation. If this is the case, there's nothing to be done.
2. Your plan matches each payroll and then does an additional calculation at the end of the year. We call this a true-up. It's not required but many plans do this. If this is the case, then you'll get your additional match under this calculation.
Your HR dept can tell you which applies.
