P6 Web EPPM - Financial Periods - Overlapping Error

Hello, when I create a financial period batch in Weeks in P6 EPPM, I get an error "Failed Saving Data. Cannot create overlapping financial periods". It only allows me to create (10) weeks, no more, adding week 11 creates the error. However, I can create a batch for many months at a time with no problem. In my opinion, this error should not happen while it creates its own batches. I can see if I entered it manually and I overlapped some dates.

Does anyone know how to fix this? Or have a suggestion on any workarounds, using months? I need to record my financials in weeks. I'm familiar with using batches in P6 professional, it shouldn't be any different on the Web version. Please advise.....
