BUG - Cards in collection being changed

So it's the second time I notice this where cards in my collection change to be a different one: Example: Just now I noticed I had 2 Pre-release Ramunap Excavator listed while I know I listed 2 Buy a Box versions of the card. Another example: I have several full art lands from Zendikar, and the other day while I was looking through the list, the basic lands were all incorrect, where the numbers were correct but the version was not. All 5 basics were somehow switched to be a normal frame instead of the Textless ones. Is this something with the App? or perhaps with the source (scryfall)?
