ERROR booking DL Test Slot

I have got my learner licence from Thane, louiswadi RTO office and 1 month has passed. Now I’m need to take the driving test, so I attempted to book slot for that and it keeps displaying the message "Entered Application No. is approved. Slot booking is not allowed". I tried with both application number and learner licence number and same thing. I have sent you a screenshot of the same. I request you to kindly look into the matter and provide a suggestion or solution. My application No is 1538447419. Learner Licence no. is MH04 /0044493/2019. My name is Bradford.
