Tetenal E6 kit FD and BX 2 crystallized

[jumanji]

I'm using the Tetenal 3 bath kit and it was opened nearly 5 months ago. The concentrations were keep in the original bottles without Protectan, and the remains are for 1l working solution. Today I take the kit out and notice that the First Dev and BX part 2 have crystallized. I tried to heat them up then shake but they were not dissolved. Are they still working or dead?
