Line Graph does not draw complete line

[AlejoSG1]

Hi everybody, I'm new to the community, I am having trouble finding the solution for a problem that I have (or can't find the right words to describe my problem).

I want to have a line graph to compare the cumulative number of "contracts" by time and by a category ("ADMINISTRADORA DE FONDOS"). I am using this DAX to calculate:

Negocios Acumulados = CALCULATE(

    COUNT(default_1[NOMBRE]),

    FILTER(

        ALLSELECTED(default_1),

        default_1[FECHA REGISTRO] <= MAX(default_1[FECHA REGISTRO]) && default_1[ADMINISTRADORA DE FONDOS] = MAX(default_1[ADMINISTRADORA DE FONDOS])

    )

)

When I use the table visualization, it shows the data correctly, but in the line graph there are points that do not connect properly in line as the following image:

What am I doing wrong?
