There is a Known Issue regarding the KV Page Process configuration.
After applying the upgrade, your entries for each Key Value will be lost.
Please Refer the above wiki link for the solution.
The shortcut key Ctrl Q blocks out the other fields in the validation screen and hinders the ability to edit them after using ctrl Q for the first time despite the value for the field is set to false in application.properties which is located in \Ephesoft_Installation_Directory\Application\WEB-INF\classes\META-INF.
We will need a hotfix to fix this issue with help of development team.
