I had similar issue but figured it out (same as noted in prior response). The problem I'm having is mapping the time dimension -- I tried to map to a specific format (i.e. pick Jan-20) -- it fails saying it is expecting a 2 digit month. When I map it to start date, it loads 33 records and fails 78. In essence most of the start dates are outside the TIME range of the model. (i.e. start in 2012 when the model time scale is Jan-19 to Dec-21. I'm ok to move forward -- just wanted to validate. Now I'm assuming I could change the scale back to Jan-2012 but that would make the model unwieldy. Any help would be appreciated.
