Tabular model measures datatypes got changed to unknown after publishing to Power bi Premium gen2

Tabular model measures datatypes got changed to unknown after publishing to Power bi Premium gen2.

I had measures under a Caluclated table named _Measures and all the measure datatypes have become uknown when I deployed the model to premium and then connected the model via tabular editor to save it as a BIM file .

This is what it shows in tabular editor
