It's definitely a good idea to double-check with your benefits department to ensure that everything is in order on their end. It's possible that there may be a payroll issue that needs to be addressed.
In the meantime, it's a good practice to keep track of your
pay stubs and double-check that everything is correct each pay period. This way, if there are any discrepancies, you can address them as soon as possible. If you find any issue, report it to the payroll department or HR, and they will look into it and rectify the situation.
Hope you managed to figure this out.
