Kindle fire HD 10 and Calibre Issue with date

[Togetic]

Hi, I have a Amazon kindle fire hd 10 (7th generation) and i'm having an issue. When i send books to the device via Calibre, when i click on the device on the calibre menu it shows the date added as 12/31/1969 for anything that is added not matter what date. I have been emailing Kovid Goyal from calibre and he said it's the issue is almost certainly caused by file timestamps being incorrect on your Kindle, but i don't know how to fix it. I've factory reset the kindle per his request and still the problem persists. I have older kindles and don't have this problem, it's only this kindle. Does anyone have any ideas how i can fix this? Could it be caused by an update from amazon or even Calibre? Because this problem just recently started to happen. Thanks
