Importing photos with the same file name messed my catalog and pictures

Context:

I imported 100 pictures in my Lightroom CC catalog those previous days, here the way I did it:

1. I imported pictures in my iPad film roll from my SD card reader (My camera is a Fuji XT2)

2. I imported them in a new folder in Lightroom CC on my iPad : "2019.07.02 - Paris"

Problem:

Now some pictures of that folder (still using Lightroom CC both on iPad or iPhone) are confused with pictures from another CC folder "2019.02.12 - Paris" which have the same file names (automatically generated by my XT2 camera... the DSCF1008 from February is displayed instead of the DSF1008 from July) but imported last February.

Back at the office I opened Lightroom Classic CC, and same problem, even worse... It has overwritten the files imported from adobe cloud in the Ligthroom CC folder on my mac with the files from February...

It's a complete mess, I still have my pictures on my SD, so it's not a catastrophe but it's very worrying in the future!!!
