Hi Penlew,
Thank you so much for reaching out. We will need some more information to be able to assist in this case, e.g. are you importing timesheets via a 3rd party application and are you using Automated pay runs or have more than one pay schedule set up?
Also, If you have created an ad hoc pay run for a past date this may have affected the next scheduled pay run date.
Please let me know the answers to the above questions or if you would prefer please feel free to contact our support team as they will be able to walk you through the steps to resolve your query.
Thanks,
Rebecca
