One thing I can suggest on making similar mistakes. Use the loop feature and segment that specific section where mistakes happen. Slow it way down and play only that section on repeat, not the whole song. When accuracy starts to kick in, speed it up slowly until at normal speed. Once you have the difficult sections nailed, replay the whole song.

My advice is playing the whole song should be fun. If you're not having fun, it may be time to move on. You can always go back to it at a later time.
