P: Importing Files into a folder with the file system date rather than metadata date?

I had an issue with lots of repeated files and in order to fix it I wrote my own script to calculate a hash on all files and then check which are the same. This worked very well and with it I found that I have the same exact file imported into different folders...

In my setup all the files enter those folders through an import on Lightroom.

When I digged further I found out that:

1) the files have the same MD5 hash
2) they are exactly the same
3) they have the same EXIF data and it matches reality (CREATED DATE)
4) They have a different date on the filesystem
5) The file was imported to the date the file has on the filesystem

I am very surprised with this. When we move files around the file date changes but it seems that Lightroom is importing based on that and not on the METADATA inside the file.

This is happening for .JPG 

Is this normal behaviour?

I have the latest release of LR Classic 9.2
