What model device you have and how old is it?
Have you tried doing a factory reset? Or at least try a system restart...or unplugging the device for 30 to 60 seconds?
That typically is a symptom of a corrupted memory cache. This can generally be cleared up by restarting the Roku, as suggested by @JWS9518.
Depending on your Roku model you'll find the "System restart" option under "Settings > System > Power", or on models without a Power option, under "Settings > System".
Note: If you have a Roku TV with "Fast TV start" enabled, turning the TV off and back on just puts it into and out of a standby state and does NOT give you a complete restart. Use the menu option above.
If a restart doesn't do it, or if you don't have sufficient control with the remote to navigate the Roku menus, you can also restart by pulling the power plug to the Roku for a few seconds then plugging it back in and waiting for it to restart.
