Some of the imported presets not showing up

Hello! I changed my macbook and I wanted to transfer my presets from the old one to the new one, in lightroom classic.

I tried to import presets in the develop module but some of the presets won't show up and when I do it again it shows: already imported.

"Show partially compatible" is checked but they do not show. I also tried to put them in the folders but again, they do not show.

I bought some presets and when I import them to the new pc, it only show half o them.

Can someone help me?
