Campaign Milestones Bug

When I first started playing the campaign for Star Wars Battlefront II my PlayStation 4 was not connected to the internet. So for the first playthrough I found some of the hidden items on a few of the levels (2 on The Cleaner, 2 on The Battle of Endor, and 2 on Under Covered Skies) but did not fully complete the campaign. When I was finally connected to the internet I started the campaign from the beginning and after several play throughs discovered all of the hidden items with some help from online sources. Now that I look at the Campaign Milestones on the Career tab it does not show that these initial hidden items were tracked as being found but when I look at the Single Player -> Campaign -> Main Story -> Select Mission Tab it shows that all collectibles have been found for every level that has them.

I tried contacting EA to fix this and earn the three Campaign Milestones (because I have achieved every other milestone and would love to see the overall progress reach 100% rather than 99%). Their suggestion was to clear my cache but I wasn't sure how to do that without deleting my profile data which would reset everything which is not ideal because I would need to pay for multiplayer access to achieve everything again. I do not have a PS Plus subscription so I can't save an online copy and redownload after trying the campaign again without the profile data and I'm not even sure if that would fix the problem.

If you guys have any ideas on how to fix this that would be greatly appreciated otherwise I'll have to settle for pride in 99%.
