Maxima is happy to let you create different objects
with the same name, but then it doesn't handle them
consistently. This is a bug. At this point the only advice
is just to avoid creating things with the same name
(although it can happen inadvertently all the same, e.g.
when a function argument coincides with the name of
a declared array).
Sorry about that. Every now and then I think about
how Maxima's treatment of subscripted objects could
be revised. I haven't gotten very far.
