Or not, maybe your encryption+compression has triggered a Shannon Singularity! ;)

Now, seriously.  I've seen odd size reports for cache drives before. Can you try running "zdb" and

Maybe detaching and reattaching the cache drives from the pool might help, in case something related
to the cache drives is creating the confusion.
