st: Bug in margins

I am analysing a logistic regression model, binary outcome. I want to
analyse the adjusted proportion of the outcome for a binary (0/1)
covariate.
I run the logistic model followed by margins
. logistic dod30dgr i.lapscopiintent alder aldersq........
. margins lapscopiintent
I get an error
'lapscopiintent' not found in list of covariates
r(322);
If I put i. before the binary variable I am interested in
. logistic dod30dgr i.lapscopiintent alder aldersq................
. margins lapscopiintent
Predictive margins Number of obs = 166811
Model VCE : OIM
Expression : Pr(dod30dgr), predict()
Delta-method
Margin Std. Err. z P>z [95% Conf. Interval]
lapscopiin~t
0 .0015466 .0000985 15.70 0.000 .0013535 .0017397
1 .0011487 .0002518 4.56 0.000 .0006552 .0016421
I assume this is a bug?
