st: reporting results from a multiple imputed data set

Hi everyone,
I need a recommendation.
I have a multiple imputed data set (N imputations) and with a set of dummy variables (M years). Let’s take year dummies as an example. Stata omits of the M year dummies due to collinearity.
As it turns out it is not always the same year dummy in the N regressions. In conclusion, when I apply the Rubin Rule I get an estimate for all N year dummies.
Which way is the correct one: Shall I just exclude one dummy prior to running the regressions or do I report (after application of the Rubin Rule) coefficients for all M dummies?
I hope I made myself clear.
Thanks!
