Blank issue

[Dylandejong]

There are a lot of pages dedicated to explaining how to solve this issue (blank in slicer), but non about why it needs to be solved in the first place.

therefore, why do you need to solve the blank issue? i.e., What problems does / can it cause? (E.g., does power BI gets slower when due to it?)

It's not actually an issue.  At least not technically. Maybe an eyesore to some, but very helpful to others (especially when doing whitespace reporting)

It's linked to the implementation of the Vertipaq engine when it comes to representing different join types. Happens when you link tables via a key that may not be fully covered on both sides of the link.  (similar to a left or right join versus a "regular" inner join.
