Hi @arch.matef
I think your problem is that you aren’t using a separate date table. Best practice is to use a EDNA Date Table within your model.
here is the link
Extended Date Table (Power Query M function) - Power Query / M Code Showcase - Enterprise DNA Forum
The link that you stated is using the EDNA Date Table not the fact table dates
Make sure you mark your table as a date table.
thanks
