This is a screenshot of before/after a complete cycle. Shouldn't the Uranium from the beginning become Depleted and not disappear. This is the second 4 to 1 (4 Depleted Uranium to 1 Uranium) setup that I've had this happen on. Sadly I didn't screen shot the other and eventually blew it up when trying to go +9000 
I think I've also experienced this on a 2x 3 to 1 Breeder (has 2 sets of 3 Depleted Uranium to Uranium) as well but am not sure since that was the first time I realized I was missing the Depleted Uranium (I think 1 turned to Depleted Uranium and the other vanished in that case). In all cases the Isotope Cells I was breeding worked correctly.
