Unable to file professional tax for Maharashtra - website simply shows "No Data" for Periods

While trying to file professional tax returns on mahagst.gov.in, we seem to be getting stuck on the step where the time period needs to be selected. After selecting the financial year, the website simply shows "No Data" for Periods. Screenshot attached.
Can anybody help? Has anyone successfully filed PT returns this month (July 2018)?
