Why my Integer Fir on filterbuilder gives me zero coefficients?

I am trying to build a simple fir filter for impplementation on FPGAs. I want to use integer coefficients to simplify and minimize hardware resources. filterbuilder only throws me zero coefficients no matter configuration a use, if a I set the fractional bit numbers to 0.

Could you post the coefficients (at least the min/max values)? What is your input data type? For implementation onto an FPGA, you do not have to restrict yourself to integer values, you can use the appropriate integer and fractional bits needed for the coefficients and input.
