Hi skc-shalin.
Having the right information on an invoice is imperative to keep your reports and reconciliations correct so you can keep saving time with QuickBooks Self Employed. I'd be happy to help you with getting your invoice to show the right dates.
When QuickBooks Self Employed isn't working the way it's meant to could be due to your browser health. I recommend doing some browser troubleshooting as there could be something happening that's preventing your QuickBooks from working properly. The first step would be to clear your cache and cookies for your browser. Once that's done I recommend opening QuickBooks again in a private browser such as Google Chromes Incognito mode. If that doesn't work sometimes trying a different browser all together can work also.
If these steps still don't fix the issue I suggest reaching out to our support team so they can take a deeper look. You can reach them by Clicking on Assistant in the top right corner.
Have a great day!
