Missing Data Discs

I have completed 100% of all planets and all locations. I have finished all the holotactics games. However, I am missing 2 data discs. My map shows me the location of the Moldy Depths when I click on the data discs in Inventory, but my map says I have already collected the treasure there. Secondly, I have completed all holotactics games, but my map says I have not as the star is blinking next to the holotactics legend on the map. I am missing on purchasing one item from Zee's shop. How can I get these glitches fixed so I can achieve 100% on my playthrough?
