Legend Widget Size

[RodrigoFelga]

I have a Map published that uses a custom font as simbology. For a specific Layer I have Simbology with font-size 152pt and font-size 2,4pt and that causes the legend widget to display only the larger symbols, the other symbols is so small that appears in legend widget only a blank image. Is there a way to set the font size of the legend widget to display all symbols?

Below is the symbol configuration in arcmap
