Lots of glitches

I have cute cut on my iphone and i absolutely love it. I’m able to make video edits so quickly on it. When i heard they released a version for the Mac, i knew i had to download it. So I did. Worst idea ever. I’m currently trying to make a short 2 minute video, but cute cut wont let me add up to more than three media items. When i do add a fourth media item, it doesnt even show up in the actual video. It’s basically like its not even there. Also, the videos i do have in the project don’t play smoothly like they’re supposed to. And if i mute the sound on a video, there’s a bunch of weird clicking noises that don’t go away.
