How to resolve "An item with the same key has already been added" issue?
I am getting an error message that says "
" when I try to update a record.
I have tried to troubleshoot this error by reviewing the data in the system and ensuring that there are no duplicate records or keys. However, the error message still persists.
Could you please help me to resolve this issue?

Hello,
The reason for this issue was in the duplicates in the SysSchemaUserProperty table related to the "false" state of the "Enabled" property of two DCMs. As a result of this the system couldn't form structure for all DCMs properly and this resulted in the error messages in two modal boxes you presented in the screenshot.
