Updating my library only add movies

Maybe I did something wrong. One month ago, I created my library from a HDD, and it worked fine. Few days ago, I got a new HDD, so I choose to reorganised my movies on my two HDDs. Hence, I added and removed some movies on the first disk.

Then, with OSMC, I updated my library again. It found all the new movies, as the last time; but, it didn’t delete the movies I removed from the HDD.

What’s the correct way to update the library?

Thanks in advance,

Please use the forum search feature, you will see a recent discussion about this. You need to clean your library.

Sorry! I didn’t use the right keywords, my bad!

Thanks anyway!
