D&G strings sound flat/muted in comparison to E&A ...

[Bassist13]

I recently changed the strings on my bass from Chromes to TI Jazz flats and now the D&G sound flat or muted but there is no debris or anything to mute them.

title says all. I did a search on here but maybe I'm using the wrong terms.

My Chromes do the same thing. Great sustain on E and A, just a plunk & plink on D and G respectively.

is there anyway to improve the sound, like file the nut or adjust the bridge ?. I'm not to handy with the finer adjustments on a bass.
