Even at lower dilution of about 2.2g/L, the little white crystal stil persists.

That makes it even more likely to be an insoluble impurity, rather than undissolved sodium fluoride.

I’d just let it settle and use the clear liquid.

Got nice clear liquid after running it through a filter! Thank you
