In #1959 I've introduce a bug that SDK has hit in dotnet/sdk#29131
Previously, the method was returning error for the first mismatch:
command-line-api/src/System.CommandLine/Parsing/SymbolResult.cs
Lines 132 to 135 in 82273cb
After my changes it was the last one. This fix just helps me to unblock the SDK update, it does not solve the problem of producing multiple errors by a single validator.
