I am new to this research world and very confused. I submitted the manuscript to a journal and a few hours after I submitted it, I realized that I had made some mistakes. While I was working on editing the format, I accidentally changed everything back to non-italic. I then italicized many places where it was needed, but not in the reference list. When I looked at the reference list after sending the manuscript, I noticed that mistake and some punctuation mistakes. I sent a new version later, but the day after the editors wrote to say that the manuscript had passed the desk stage and the originality check and would be sent to the reviewers.
I asked about the version they checked and it was the first version. The editors told me that some errors can be corrected in later stages. However, I am worried that my manuscript would be rejected due to this technical error. Please tell me your thoughts on this. This is not a top rated journal and it is my first research. Some professors told me that this should not be a fatal flaw. Thank you.
