Yeast Still in Suspension?

[LakesideBrewing]

I have been washing yeast for a few years now but I have never seen this before. I harvested and washed some Conan Yeast on 8/10 and have kept it at 36 degrees since then. I have about 400ML in a mason jar under sterilized water. I'm brewing tomorrow and took the jar out of the fridge to wake up the yeast and noticed there is still a lot yeast on the top of the water. So I have 400ML of thick yeast on the bottom, clear water on top of that, then a good amount of yeast on top of that. Anyone seen that before?

Thanks,
Mike
