C41 part A sedimentation

I've just bought a C41 developer pack, with its part A having sedimentation at the bottom of the bottle. I prepared a 500cc developer using this pack, which it seems that its part B and part C are fine (without sedimentation or color/odour change). But the prepared 500cc developer's color is just colorless, like water. A photo has added.
I wanted to know the cause. Is it because of the sedimentation? Can i do sth to eliminate them? Like warming up the bottle content? Or it's because of the part C of the package?
A photo of the Part C has also added.

Thanks in advance.

It is normal for part A bottles to have some undissolved chemicals at the bottom. All of mine has that. I think it is the way it should be. Don't warm up the part A. Just throw away the solid once you use up the liquid. The mixed (part A, B, C, water) working solution is almost colorless. It has a very light color that I can't describe but it's almost colorless. Keep in mind part C once opened will go bad in a month or two. Its color will get darker and darker and eventually black.
