Please do not delete the changes unless you are sure that they need to be fixed.

Hi, I made some mistakes in my edits as it was my first time using OSM. Sorry for any inconvenience. Let me know if you want me to revert those changes or it is already done. Again sorry for the mistakes, I will make sure similar mistakes won’t happen again!

I think those deletions were done mistakenly. I'll keep an eye on the annotations you mentioned to make sure are not changed in the future.
