Wrong repo size after cleaning up repo

I am getting a wrong repo size of 1.2 Gb on the repo.
The repo size before I believe was 550 Mb, so I did a clean with BFG repo cleaner.
But today suddenly the repo looks to have 1.2Gb size.
Although when I do "git count-objects -v -H" I'm getting this:

count: 13
size: 80.00 KiB
in-pack: 16314
packs: 1
size-pack: 259.45 MiB
prune-packable: 0
garbage: 0
size-garbage: 0 bytes

I'm not sure how to fix this issue. The strange thing is when I actually download the entire repo, the size is only 120.6 Mb. Although I've seen from other issues that this is something Bitbucket support can fix on their side. So hopefully you can help me also with this issue.
