Commits messages numbered only until 10 when squashed

Git version: 2.11.0

THE CASE: I have 15 commit to be squashed (the hashes are real, but the commit messages were changed for privacy). When it's rebase interactively squashing all the 15 commits, the numbering goes from 1 to 10 and after it starts again from 1 to 5.

- The first line says "This is a combination of 5 commits" but the
real amount of commit is 15.
- #5 coincidentally is the last commit in the concatenated messages to
build the new commit message
- The order of the commit messages joined were: 1, 2, 3, 4, 5, 6, 7,
8, 9, 10, 1, 2, 3, 4, 5

WHAT WAS DONE ? git rebase -i 4e4f37c3~1

pick 4e4f37c3 s 72742a70 s db800d70 s 2bcd475a s 5e5eb85f s 4422b1e5 s af19b0e2 s 3d64165b s faeb2ce9 s c7dc6b38 s edeff8d9 s bd451d5b s 851bf828 s 9cae1f95 s b79466fb

WHEN THE COMMIT MESSAGE IS EDITED: The commit hashes are real, but the messages were changed for privacy.
