I may be taking this completely out of context, but if this is the case,
there is an argument that logistic regression is inappropriate, and
cloglog regression (which has a hazard rate interpretation) would be
better. (I don't know if this is appropriate for your data and research
question.)

I would consider doing something about this, for instance combining
category 5 with another category, if only to avoid dropping so many
cases.
This causes problems in the xtlogit too, where the cases are not dropped.
