Repository size doesn't refresh

Hi,

I've recently got a warning about the 1GB limit on my repository, so I decided I reduce the size. I did it with the hg convert extension in my local folder, I've excluded some binaries. The new size is ~250MByte. After that I stripped the whole repo on the web and pushed the new one. I've tested with cloning the new repository, and the size is correct (250 MB).

The problem is the warning is still present, and when I enter into settings, it says the repository size is still 1.3GB. What can I do? Do I have to delete the whole repo and recreate it?
