Well then i would suggest you to delete the entire download and clear the PS4 console cache.
Please see the steps below for the recommended steps on how to clear the cache on each console.
PlayStation 4
- Completely shut your console off
- Once the console is completely off, unplug the power cord from the back of the console and let sit for at least 5 minutes
- Plug the power cord back into the console and power it on.
After the cahce is cleared start the download from the very beginning.
Let me know how it went.
Good luck.
