Commits counter and project size not correct?

Hi,

i have a project which had a lot of commits and the size was very big.

So i started to rebase the commits and added optimized files.
Now i only have 8 commits (shown if i clicked to `Commits (108).

The size of all files are actually (in sum) 2094,34 KB - but the frontend on Project displays 6,3 GB.

So i don't understand why the project size and the commit counter is the same than in screenshot above?

Have a big sized repository with many commits.
Rebase the commits locally with delete option and push it to master branch.

The project size and the commit count is wrong.

The project size should be smaller and the commits counter should show now 8 commits - not 108 commits.
