Wedge product

Hi,

I am new to Maxima so I apologize if the following question is trivial.

Why does the wedge product command in package itensor behave like this:

(%i2) ishow((o([j],[])*s([1],[]))~o([k],[]))$
(%t2)                              s  o  o
                                    1  j  k

I would expect the answer to be zero, not
s([1],[]))*o([j],[])*o([k],[]).

Anyway, at least if I assign components to s then the wedge product
works as I expect:
(%i3) s(l1,l2,[l3]):=kdelta(l1,[1])$
(%i4) ishow((o([j],[])*s([1],[]))~o([k],[]))$
(%t4)                                  0

Is the former behavior a bug or am I getting something wrong?

I am using Maxima 5.17.0.


Best regards,
