Possible Bug in Units2

I recently downloaded Miscellaneous`Units2` and started using it and some
problems arose which only happen after Miscellaneous`Units2` is loaded. The
following illustrates the problem.

In[1]:=
f[a_?IntegerQ, b_?IntegerQ] := Part[t, a] - Part[t, b];
In[2]:=
Needs["Miscellaneous`Units2`"]
In[3]:=
f[a_?IntegerQ, b_?IntegerQ] := Part[t, a] - Part[t, b];
Part::"pspec": "Part specification \!\(b\) is neither an integer nor a list
\
of integers."

The function appears to perform correctly but I dare not use Units2 with the
error message showing.

Sorry if this has been pointed out before but it took me some time to
establish.
