This means to rescan or reindex the blockchain from the beginning. Sometimes individual wallets sync with a side fork and don't establish consensus properly. This happens with Bitcoin as well from time to time.

You can do this from the command prompt. Or you can go to the digibyte installation folder and then hold down Ctrl and right click. Then select "open command prompt front here". Then type " digibyte-qt.exe -reindex"

Let us know if this resolves the issue.

Have you tried restarting the wallet with the -reindex or -rescan command?

Are you on Windows or a Mac?
