Limit of Columns in Matrix Object

Hello,

I have one question. When I try to create a matrix object with two dimensions (one by rows and the other by columns), the object don't show me the 100% of values contained in the dimension 2 (columns). My question is, The matrix object in Power BI have a default restriction of showed values in columns ?

Like this example:

In my dimension 1, I have 3 values, the matrix show me 3 values, so this is ok.

In my dimension 2, I have 50 values, the matrix show me just 43 values, so the object truncate my value columns.

Thank you for your answers !.
