Hi Delmaris. I'm Greg, an Independent Advisor here to help until this is resolved.
See troubleshooting steps for MS Ergonomic Keyboard:

Some methods to try to reset to defaults:

http://www.thewindowsclub.com/reset-keyboard-se...
Try the Keyboard Troubleshooter at Settings > Update & Security > Troubleshoot.
If this began within the recent past, See if you can System Restore to a point before the problem began: http://home.bt.com/tech-gadgets/computing/how-t...
Check which Updates were installed at Settings > Update & Security > Windows Update > Installed Update History and try uninstalling any from around the time this started. If they return and cause the same problem then hide them with the Hide Updates tool: https://www.howtogeek.com/224471/how-to-prevent...
What also might work is to go into Device Manager, reached by right clicking the Start button, choose the Keyboard device, on Driver tab try Updating the driver automatically.
If this fails from the same location try rolling back or Uninstalling the Keyboard driver, which works in a surprising number of cases where keyboard is messed up by Updates. Restart PC to reinstall driver.
I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
