Problem with Custom date table relationships

Question

Hi everybody,

I connected a custom date table to my signup_date table now most of the values are shown but 135 are not, they are marked as blank.

Now the range of the two tables corresponds, there are no duplicate values in the custom date table, my signup_date table has a duplicate but it is on the many side of the relationship, the relationship is marked in the editor as on top the signup_date table and then the custom date table so the relationship is marked as one to many, and the values are both US time zoned.

Does anyone understands why these blanks are showing up?
