Going by the photo, I'm going to hazard a guess that it wasn't dried entirely during manufacturing and retained some water, or somehow got a little moist over time. But that's a wild guess. I agree it doesn't look the greatest. The sludge in the concentrate is a bit odd; perhaps there are other impurities as well. The greyish color of the flakes is weird; catechol tends to be more brown in my experience.
Looks normal to me. I get the same. Concentrate is very pale reddish and if pulled into a very thin syringe like yours in the photo, it's nearly colorless. In a bottle, it's more pale red.
I would suspect the yellow is part of the sensitizing and anti-halation dye package of the film that washed out into the developer. The subsequent color change might be normal oxidation of the developer, which is indeed orange/brown.
Mine is clear as well.
Here's my concentrate (part A) in glycol to the left, and a freshly mixed working solution 1+1+100 in tap water to the right:
