Before we start with the initial step, let's review the Report period and make sure it's correct. This can be the reason why it doesn't show by one year.
If the same thing happens after reviewing the said information, we can try a few browser troubleshooting steps to resolve this.
Let's begin by using a private window to see if you'll get the same result. Below are the keyboard shortcuts that you can refer:
Google Chrome: press CTRL + Shift + N
Mozilla Firefox: press CTRL + Shift + P
Safari: press Command + Shift + N
If it works, go back to your original browser and clear the cache to make sure your browser functions more efficiently. Otherwise, you can try other supported browser to help narrow down the cause of this behavior.
I'd appreciate if you'd let me know the results. I want to make sure you're able to get the reports done. Just leave me a reply below for additional questions. I'm always happy to help.
