Error While Saving Time Layout Sets

Summary

Got an error when trying to add multiple attribute field in time matrix

Content

Error message: You can't add this time card field because the limit has been reached for the time attribute data mapped to this field

What I already did:

Run Diagnose and Correct Time Issues process with below parameters:

- Action: Diagnose and correct
- Type: Layout set
- Date Range: Current day / All previous weeks
- Available Values: empty

But I still got the error message and unable to continue.

Anyone facing the same issue? Any inputs / suggestions are welcomed, thanks.
