Bro, the first time you got reject in 14 days, I assume you did not even get biometric correspondence. It means your visa application was not even processed by VO. It probably got rejected at document verification stage because you did not provide all the documents required. Normally from application to start of eligibility takes a minimum of 15-20 days. You applied on 17th so your eligibility review is likely to start around 3-7 Sep if everything is alright regarding docs. If all goes well, PPR by around 7-10 Sep. This is probably the best case scenario. So you need to wait a little more. Take extension if required.
Regarding your profile it shows by default that medical and biometric is not required. But later they update it. If you have given all the docs you just need to wait a bit more. It's been around 16 days since you submitted and generally even the best possible processing time is around 18-20 days.
All the best
