Thanks for the report.  However, that is not a bug.
Your first example really is an error.

As documented (see the "character classes" section of "info tr"), when
translating (i.e., not deleting), if you specify "lower" or "upper"
in the second set, you must specify "upper" or "lower" (resp.) in the
first set -- and it must be in the same relative position.

Dear GNU,

Not sure if this is bug. But I think first one is legal command that is logically similar to second which works



Thank you,
Raj.

[raj <at> rajvista ~]$ echo "Raj" | tr "[[:alpha:]]" "[[:lower:]]"
