The first time I had this change was when I raised cse ...I thought since I paid the RPRF upfront, it had to do something with review and upload at the second stage.... but m just guessing....
Right now my BGC is at Not applicable stage....
the second time was when they asked for schedule A, I saw those changes ! Just two days back it changed to uploaded and still the same till now. Quite strange tho! I pray it's a good sign
