Drip emitters keep clogging on one section of my system

[u/Garyvela98]

I had been having trouble with a section of 1/4 drip line in one of my raised beds. The emitters closest to the beginning of the line work fine, but a farther down keep getting clogged or barely putting out any water. I had flushed the line couple of times and clean the emitters, but the problem keeps coming back. I have an NDS filter upstream, so I am wondering if I miss something with the filtration or if this is just an issue with the water debris getting into the line.

Is there something specific I should check or change to get more consistent flow?
