File timestamps not saved

I installed GrapheneOS on my newly purchased Pixel 9 Pro a week and a half ago and files are not retaining their timestamps or other Metadata. This happens with photos taken with the GrapheneOS camera, Google camera, downloaded photos, and even photos transferred from another device. This seems to happen with videos and other filetypes I download or transfer too. Has anybody experienced this before? Is there anything I can do to remedy this before attempting to reinstall GrapheneOS?
