I understand the Intel® Graphics Control Panel is not properly displaying settings.
Let me apologize for any inconvenience this issue may be causing to you.
In order to help you better I would like to gather more information about the configuration you have in the computer. Please attach to this thread the .txt file the Intel® System Support Utility will generate https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility
If possible also attach the Intel Graphics Driver Report. This link will show you how to generate it https://www.intel.com/content/www/us/en/support/graphics-drivers/000005848.html
Was there any software or hardware change before the issue started happening?
