Lightroom 7.4 issues with presets

I recently got a new Mac and am trying to move my presets from my older Mac to this new one. When I export them to a drive and import them in Lightroom in my new computer, they say they have been imported but they don't all appear. Much of what I found for solutions are for Lightroom Classic and the one option I found for 7.4 to uncheck 'hide partially compatible presets' and restarting the app didn't yield any results. I read that it could be issues with the profiles associated with the presets but haven't found where to address that issue at either. Any help is appreciated!
