My edit was rejected for this reason:
Let's wait until we find out what the symbols mean...
Which I failed to make sense of.
While the user who rejected the edit, made the same edit in the body but refused to edit the title. They could simply approve the edit and re-edit afterwards. The question is now edited to something similar to what I suggested.
I'm not trying to make a mountain out of a molehill but I realized the rejected and approved edits of a user are recorded under a so-called "editor stats" and this is the third time someone rejected my edit, mistakenly. I just think they should be more careful about it.
