OK, this is huge, and needs to be corrected in your help files/docs/video. HT needs to specify that the files need to be “Merged” and not “Replaced” or “Overwritten”. It would have save me half a day’s worth of work.
In your current help post you give this instruction:
“A message may popup and warn you that there are similar files already on your server, you will need to select overwrite to add the new files.”
