Same as you, I thought I had inadvertently added other family members to the application. It must simply send a default page through until it sorts itself out.
The UK Police check request stayed on there so I uploaded the old ones that we still had on file and almost instantly it disappeared from the check list!
Coincidence I feel
I still haven't received any emails but being Sunday I didn't expect to. I could see 'Bridging Visa Granted' After logging back in to see how the application was progressing.
It would be nice to see a time line from all who have received their's to enable us to gage roughly how long we should expect to wait before getting worried.
Thanks and good luck to all those about to apply and those waiting on the answer.
