Possible SD card issue?

<span style=”color: #333d42; font-family: -apple-system, BlinkMacSystemFont, ‘Segoe UI’, Roboto, ‘Helvetica Neue’, Arial, ‘Apple Color Emoji’, ‘Segoe UI Emoji’, ‘Segoe UI Symbol’, sans-serif; font-size: 14px;”>Had an issue earlier today where my X4 wouldn’t go in to sleep mode, it just kept going into booting Crosspoint screen. So I did a reset and it seemed to fix it. Now every time I put it to sleep it opens with no open book and no recent books. However if I go to the book I was reading in my files it opens to the page I was at. Is this something I need to delete that Crosspoint folder on the SD card or is the SD card having issues. Keep in mind I’m still using the included 32gb card that came with the device and yes I k ow I should have switched to a new one. But is this something fixable now or I’ll need a new SD card?</span>
