RMark with Mark-Resight models: bug?

I am getting the following message when trying to run the immigration-emigration mark-resight model (IElogitNormal) using RMark:
#############
Error in process.data(DATASET2014Final, model = "IELogitNormalMR", counts = list(`Marked Superpopulation` = c(28, : all 0 ch encountered. MARK will not accept them
############
However, the IElogitNormal mark-resight model accommodates all 0 chs and these models run using Mark directly.
Thank you.
