Why doesn't this FGameplayTagQuery have a AutoDescription?

FGameplayTagQuery UInvFunctionLibraryPlusStructs::TestTest(FGameplayTagContainer Tags)
{
return FGameplayTagQuery().MakeQuery_MatchAllTags(Tags);
}
Above code was a test to make sure I was using TagQuery correctly. It does give a query that seems to be working correctly but it’s AutoDescription variable is always empty (instead of saying something like “ALL(color.blue,color.green,color.red)”).

When I make a TagQuery in blueprint it will have the description as expected.

What’s the difference here?
