Cannot seat Timed General admission using Best seat. Error message "seat reservation failed could not find seats for specified criteria"

I created a new Facility for Timed GA and when I try to best seat the pricetype, I'm getting the error message "seat reservation failed could not find seats for specified criteria". When I go to the seat map to manually select the seat, its showing the message that " locked by this sessn reservation" When I try to choose a seat, it will reserve the seat without showing the row and seat number in subline items and I can make the payment method. 

Please advise.
