By the way, I have just tried to sync the photos in the develop module, but it seems also here, it only takes about 9 images and sets the right values, after that, it is not doing anything...

This bug has existed for many years, unfortunately, and Adobe has acknowledged it: Lightroom: Applying Auto Tone to a batch of photos loses subsequent develop settings | Photoshop Family Customer Communi… . The first post contains two workarounds.
Please add your me-too vote and details of why this is important for you to the bug report. That will make it a little more likely Adobe might fix it before the next ice age.
It seems that did the trick! So in the library module, go to Library --> previews --> Render stander previews. After that, you can set the new preset!
