A closed fiscal period cannot be reopened - D365 Operations but never closed the period. brand new legal entity

Hi  I have created a new Entity "DEV" in D 365 finance and operations (AX7) created a ledger and associated to COA and ledger calender ("fiscal"). Strangely, it shows the period status for the entity ("DEV") is permanantly closed!  I haven't done any year end close or anything!  I have used the configuration templates (set of zip files with excel) to import the configuration data!  When I try to update the period, it says " A closed fiscal period cannot be reopened."   What can I do to open the Period status!!  I tried to create a new fiscal calendar and associate to the ledger.  Still the same result! 

Appreciate your input.
